 Mark your own, here we go. Surkey, she gets everything right. Angle one, how big? 65? I agree, how come? What we're going to start to do over the next couple of days is Rob, I'm not just going to accept an answer. As soon as you tell me the answer, I'm going to say, prove it, convince me. So we're going to start to actually list what rule we use. Could you shut that door behind you for me? Thank you. Take home quiz, get it out, get it out, get it out. Question two, how big? David, what did you get? 52? I agree. How come? What's the fancy word for that? Sup? Yep. Angle three. Rob, how big? 125? Is he right? People nodding? How come? We're going to eventually call that angles at a point. Add to 360, but I usually just shorten that angles at a point. Angle five. Oh, I see letter X, that's 104. We call that vertically opposite. Oh, angle six is 76. Sup? Elementary. Angle seven is also 76, and there's a bunch of ways. I could have gone supplementary. I could have gone vertically opposite. I could have gone angles at a point. But probably most of you would have just gone sup. Mentory or vertically opposite? Okay. Angle one, how big? Adrian, what did you get for angle one, kiddo? 65? This one here? I think I disagree with you. Oh, 115? How come? Vertically opposite, we're going to call that. Yep. Did you get angle two? I agree with you. How come? We called that the z-angle, alternate interior, we're going to call that. Angle three, that's 65, yes? Supplementary. Or interior angles on the same side of the transversal, Iotsot, co-interior. Those are all the words we use for that. Tanner, letter C right there. Angle four. Okay. Because the only thing that I have is this 57. Then Nicky, it's got to be telling me what angle four is. Are they the same size? They don't look the same size. Oh, the co-interior, the interior angles on the same side of the transversal or Iotsot, they added to 180. Angle four is going to end up being 180 minus 57, 123? No, yes. Yes, people nodding. 123. Angle five is also 123, vertically opposite. Angle six is going to be 57 degrees corresponding or supplementary. Angle seven, letter C. They're both on the inside of the letter C. 104 degrees, they add to 180. Angle eight, I got a sideways Z. Angle eight, 104 degrees, they add to 180. Angle one, it's either the 55 or the 100. Joel, can you see Sesame Street is brought to you by letter F on its side? If you have a letter F, these two angles are the same size. Fangles, 100. Angle two, there's also a letter F this way. Mr. Dewick, let's use the highlight. Sideways slanty backwards letter F. So these two angles are the same. Angle two, 55 degrees, also F angles or fangles or corresponding we called that. Angle three, oh, these three add to 180 degrees. 25? 25? Angle four, how do I know angle four is 100? Ah, nice, there's two ways to get it. You could have gone those forms of straight line supplementary, but that would require you to do some subtraction. Tanner, if you spotted the Z right away, you can get it just by saying, I know they're the same, which is a little less work in your brain. Of course, you should be doing more work in your brain, never mind. What's this front page out of? Count them. 18 is Joel, right? Yeah, give yourself a little score out. Let's try that again. Give yourself a little score out of 18, it's easier to add up. How many 18 out of 18? Woohoo, back page, now it gets a little tougher. Angle five, 50 degrees, angle six, 45 degrees, angle seven, whatever 180 minus 50 is 130 minus 40, 85? Angle one, angle's in a triangle. 180 minus 42 minus 73, 65? Pardon me? I think as you learn more, as diagrams get more complicated, there's probably more ways to find the angles. Some of the toughest questions to me are a very simple diagram. There's only one way to get there. Angle two, hey, that's sub, 118. Angle three, hey, that's a triangle. It's going to be 180 minus 118 minus, what went up there, 37? Angle three, is it 25? Angle four, hey, this is an isoscelum, we'll use triangle. Oh, angle three is 70 because it's isosceles. Angle four is 180 minus 70 minus 70, 40? Angle five and six are the same thing, what are they? Well, it's going to be 180 minus 108. I have 72 degrees left over, if I divide that by two, Nicky, split the difference, each one I use has to be 36 degrees, because it's a nice isosceles triangle. And the last four, angle one. Well, I'm either going to use the 41, but it doesn't help because I don't know angle two, or I'm going to use this, when I look down there, I see a letter C, which means these two add to 180. And so, yes, I agree with whoever said that, 63. Angle two, hey, angle's on a line, supplementary. It's going to be 180 minus 41 minus 63, 76. Angle three, I have a backwards letter C. These two add to 180 because the interior angles are on the same side of the transversal. Iotsot, or what we also called co-interior. So it's going to be 139, and angle four is going to be the same as angle three, 139. What's this page out of? Out of 14, which means the whole quiz is out of. Count them, 32. Can you give yourself a nice big score out of 32, please? And making sure your name is on them, put block D there, giving yourself a score out of 32. Could you please pass them inwards?
