like enough that we can all be hard because then I can't I won't have them for future years alright that's on angle measure adjective today after measure and classify angles and identify and use congruent angles and the bisector of an angle sorry actually I'm true we have quite a few highlighted terms here so you might want to have your vocab handy to Hawaii if any of the vocab is on your sheet already the first vocab you have is a way which is a part of a line that has one endpoint that extends infinitely in One Direction solaray has one endpoint and extends infinitely in One Direction Clueless but it doesn't extend in both directions Only One Direction we can call this way m o r a m p hey those are the only two Moons for that particular way Peppers all Sabre AP which doesn't include the segment am like it's a totally different Ray but he is in that picture as well but it's not the same way as Mo or MP does that makes up so Amazon be any points of Ray ml&p if your remaining Ray LP p.m. pointment boo hey the next term is opposite rays did anybody see if they had lay on their vocab Street already and how the opposite rays survivors the trigger point on a line that plane determined exactly trouves called opposite rays since both players share a car 10 points officer brothers are collinear so if you have a ride you choose any point on the line that could be considered GM points of opposite rays jh ljk solo j h JK are opposite rays Laconia that means a lot on the same line and they have the same endpoint no headed in opposite directions hello angle Shirley to find angle an angle is formed by two noncollinear rays that have a common endpoint two wait, I'm already wavelength I think go ahead sorry I don't quite agree with what they're saying there because angle hjk is actually a straight angle animated degrees Kevin so I need to find an angle as two noncollinear rays that have a common endpoint symptoms of acute angles are two noncollinear rays with a common endpoint service they labeled x y and z so that common endpoint is called the vertex TurboTax Tanglewood BX Google okay okay and the sides are the non collinear Rays so the sides of that angle would be Xanax why those are some questions you have on your homework today or doing an angle and ask you to name the vertex and name besides so you need to be able to say the botox Evelyn is Axe and the song always x z and x y the asking to talk about how to maim the Ember so this angle can be maimed for different ways because there's only one angle in that picture you can name the angle by its vertex you can also name the angle you don't know I need to write all of that down there that's a lot of writing the vertex must be the second letter of the three letter so if you're going to need it with all three letters and then see that's why the vortex the middle letter Little Mermaid Under the three Waters water matter if there's only one angle rotated at the vertex so we could also call that just ended sometimes they putting number in the number so you can also called and the three in this case bananas put numbers in their dough so you can also call yxz doesn't matter which where you start with just so you know text mother is always in the middle can call it angle 3 because the number 3 is in the right there on the vertex with the yeah okay animal divide the planet three distinct parts the number divides a plane into three distinct parts interior exterior terminal point on the angle itself so the interior of the angle points S&R Miami interior just landed okay can you open the back door on page 36 computer yes banana going to need one for your life is the two parallel lines transversal yep yep pretty soon here yes we are going to do all of that again it's weird shovel it's okay since axanar are on the interior boys pee and or on the exterior an important skill and and and are clearly on the angle so those are the three the name of the Bible plane into three distinct parts of the interior exterior and then the points on the angle anagrammer on page 36 so our first available have a good let me know if I'm going sober the picture in your book and is a little more detail drawing of my heart Falcon parking Auditorium Library looks like a campus a high school campus okay I just got all the segments out of the picture also they want us to use the map to main almost at happy as a vertex name all the owners that have V as a Vertex so you got angle ABD ABC I will consider that Amanda. Based on the definition they just gave us they're saying it's not but I would agree CBD Super 8 near most people named with his hair add is also DBA both the same angle and terminer name any of them just say no beat Richard Marcus Mosby because there's Elmo that be actually goes for a business when here is also straight angle so oh yeah name a part of a Note 3 I didn't do that part is right here so what are the size of a Note 3 Tyson the sides of angle 3 vs angle 3 mace are the signs of angle 3 yes and let her see what is another name for angled g h l g h l another name call HG could you also College SMH yes and do you know the point in the interior of angle DBK mangle DBK name a point on the interior yes this is your anger so he is on the interior crazy I should like the word 18 pretend like it's their peers name the vertex of angle 5 for February besides that here it is play so yeah using the same diagram name the vertex of a movie named the sides of them besides write another name for angle ecl points in the exterior of NaCl h the vertex of angle 5 Quincy the side the number 5 SEPTA started fee CD and CD you can call it can CJ pay you got to start at Cedar Way CD NBC G yes Imports praderas write another name for angle ecl lace Sak pase Bearcat car Dynasty cuz there's like a million Angels at this vertex there's one two three four five six seven eight there's 10 The Bangles if that burrow taxi can't just Tennessee you can call it easy k k c e l c e e c l amazing number in at 2 but I didn't give you the number so in the exterior of CLA call s g n a r e d or e what's my place questions or not current news alright how do we measure an angle that's on homework problem degree cave that's highlighted turn angles are measured in units the green the debris is results from dividing the distance around a circle into 360 parts Sunrise 360 degrees in a circle and we is a purge to measure paintball so let's see how this goes here Sofia bring my protractor protractor Morgan align your Vortex up with the center and then either way lined up with zero now we have numbers on the inside and we have numbers on the outside because sometimes angles face this way sometimes it faith that way so right now I'm lined up with zero on the inside so he's the inside numbers and then the terminal Ray is pointing at 50 so the same old would be 50 degrees as I may not use a protractor before hey are you afraid to tell me that hopefully everybody has but you have a question corn in the other direction then your way would be lined up with this Sarah and you would have to use the outside numbers so depends on where you're angles facing it has all your protractor down on it you just want to use you want to make sure zero whichever one and go from 0 also classified Embers M&Ms Mother is C degrees is white Othello's mother is left the Mundy it is acute that is the end of measure is between 90 and 180 it is obtuse we're not talking about straight angles in this book they don't even mention the straight angle here frustrated is exactly 180 degrees Terminator Roseanne Rogers okay that's removed for Algebra 2 and trigonometry hey so we will not go back 180 what's an example to out of three whoops sorry classify each angle is Right acute or obtuse then use a protractor to measure the angles from nearest agree to me that is backwards I would want to know the measure of the angle before I pacified it I mean I can tell that looks acute or Tuesday right but I don't know and I figured you'd assemble lighter in here right mini dachshund not happen so I got to avoid letting that right into that square thing that's not yet okay how do small hey I saw it out we're just not it's because Planet able to make the notes in so it doesn't like it's okay people symbol Taylor said we do know it's right which means it in 90 degrees LOL JP is bigger than the right angle so it is obtuse and I can't use my protractor but it looks like maybe at about 10 degrees hello K100 text mnm JP and JP is smaller than mine I need to go to so it's a cheer and it looks like less than half pack of 90 45 song I called about 40 since by protractor is not cooperating okay rights show me try Okay so I will grab you a protractor how much time do you have left 10 minutes is this or 428 thing it's okay skip over that they go for that so we could maybe three more quick song one of my small protractors to use with your back pay can stay with me here real quick alright I can bring those are angles that have the same measure so am I diagram see how their symbol and their family both have a measure of 65 they also have the same tick mark that means they are congruent paint MLB Sanders here with the Devil they have the same tick marks so they are congruent base angles form a straight angle which is 180 so we could find best measure by taking 180 65 I think we're going to go there eventually angle bisector I believe this was already on your vocab list is a ray that divides an angle into two congruent angles so low body double is dividing angle XYZ into two congruent angles so it is called a bisector YZ is congruent to Verizon oh okay are congruent what is the YW dividing the big angle into two equal angles so that means it's bisecting it was going to say is that angle XYZ has a rental car yes and that something called the angle addition postulate that me having to just like the segment addition postulate officer inspecting and jkl so that mean are congruent jkn is 8x - 13 in KL is 6s plus 11 equal we can fat successful robbing people - 8 x - $0.13 that means the chew and those are equal so their modules are equal subtract 6x 13 / 2 x 12 but they asked us to find find the measure of jkm safe access 12 JK would be 8 * 12 - 13 for 96 - 13 witches 83 so that means he is Mercedes E coupe 180 yes yes yes exactly
