hey good morning this is Wednesday's mascio today you have Pages 69 and 70 in your Math workbooks and this is Page 69 you're going to need your protractor it does so the right we have the right triangle in a little faster probably but we're going to be able to do it after the first directions says draw a pair of parallel line segments problem on here not yet where I left you just kind of eyeball it or free hand sketches later on when it ask you for a couple of parallel line segments a technical way the mask the correct way to make sure that they are parallel to each other and if you remember if you watch the video yesterday when we finished this problem we talked about how we had two lines are perpendicular to the same therefore we knew that these students to blue ones were parallel to each other so we're going to use that thinking to help us instructions to parallel line segments right now in pesos about parallel with I'll let you do that later on we're going to be at the correct way right now yesterday and forgot to draw a line segment to start pretty bird call so we'll call this line segment ad and now we are going to draw new line segments that are going to be perpendicular to a V and if we do two that are perpendicular to a b then we owe to each other here for one line segments here for the second one and I'm going to turn my workbook this way to make it easier for a minute and I'm going to line up the key of my protractor here and now I'm going to look for the 90° because I wanted to be perpendicular to a b perpendicular means that hits at a right angle play dhruva. And now I go ahead and connect right now I have this line segment perpendicular to a b if I add letters here with faces we could say that line segment CD is perpendicular to line segment a b all right let's draw a second one on top of the other point that you drew put it. At 90 slide it off and connect and now we have a second line segments also perpendicular to mute a line segment on is perpendicular to line segment a b line segment CD is also perpendicular to a d the same line segment and are parallel to each other and we write that like that in line segment CD parallel do that's what that symbol mean line segment we know about perpendicular line segments to create parallel lines direct me to use a drawing triangle remember I showed you. But we don't have them at home or most of you probably don't tractor it says draw a line segment CD through Point n this is a little out of place and then I can use plain M to make a perpendicular line segments I think that's about parallel let me just draw the line and I'm going to let you do that on the third problem but we're going to do one more problem where we do it correctly select start by creating a line segment that is perpendicular to CD through Point end they're asking for parallel or perpendicular because we can use that to make a parallel so what I'm doing here if they're playing on keep your eye on plane and I'm going to line up 20 m 90 degree line Eon to line segment CD so what I've done is here CD here's the clean I got Point m on the 90° and the point right there I can't right on top of the tea that won't work so I went right below it now I'm going to does this line segment is perpendicular that is not what we were asked to do but that's how we're going to get to the line segments that are parallel because now I have cd perpendicular today if I draw a line segment parallel line segments so now we're going to draw a Alliance how to use point all right can I find 90s I want to make another perpendicular line segments slide it off I'm going to connect M and the. I just drew and I'm going to extend it a little past and like that so now what I did is I created a second line segment that's perpendicular to this they are supposed to draw a line segment parallel to CD we first through and perpendicular one then we added another one also perpendicular to the second line segment we now know that these two are parallel parallel because they're both perpendicular to the same third line segment to do it correctly, make it easy on you GF so they want one line segment parallel to x 3.2 and 1 line segment parallel to yes through Point as the release parallel line segments to EF and they will end up of course all three being parallel to each other now proper way to do this would be to draw a couple of perpendicular line segments and a right triangle doctor so I am going to let you just kind of eyeball what you think is parallel remember parallel means that the plank steak equal distance apart they never get closer they never get further apart I'm going to do the same thing just an eyeball at my best I'm going to do another one I'm going to start my book can I help you out and I'm going to make this one as close as I can to parallel also so we are all three lines parallel each other the two lines we added parallel to line segment yes that is not the mathematically correct you do have a page in the topic homework you have taste 7 I'm going to grab that alright security 7 Play Seven incredible review of some of the things we've learned. View mk7 with you three names for the marked angles in the middle so we can call this angle q r w we can reverse that order and call it angle w r q and then we can always use just the vertex of an angle all right and then it says Circle the angle greater than 90° but this one is asking you to just use what you know about a 90 degree angle to do this for not measuring them with the protractor remember in a corner of a square which of these appear greater or wider than a 90 degree angle in the corner of a square moropant take a picture of a square with slide like this so this is not greater and this is a reflex angle greater than 90° alright next one use a protractor to measure angles Pain and Spine angle and a triangle has three line up the base of the triangle with the zero and it looks like it's about 30 32 33 degrees I'm going to go with 33 remember we can degree up we can disagree here's something that just how many degrees is equal to the weekly quizzes a couple of times so hopefully you're getting it remember a full turn of 360 degree a force of that going fourth of the way around the circle is a right angle or 90° 1/2 a 360 a half of a is 180 1/4 is 90 than 3/4 is 3 times as 3 90° angles 70 and then forestford turn you have to think what's a third of 3 what is 360 / 3 + 4 360 / 3 is 120° is 120°
