say good morning this is Thursday's math workbook pages video and today on your checklist it says that you have Pages 63 and 66 so where you at work for us you're going to see that there's some pages that were skipping these are optional if you want to do them yesterday we did 60 and 61 for 60 were sipping that one but if you want to then there's a blank page 65 but again you can try it the keys online if you want to check your address and then we're going to do page 66 together direct start with page 63 it says Conrad name the angle as shown is he correct explain your answer so here you are presented with this angle before he even looked at his answer let's think about how we would name the angle normally when you name it. Three letters the letter text needs to be in the middle so the first names that I would come up with would be angle e protects capital f and then remember you can reverse it keep the acronym it also angle d e f e you can always name it just by the vertex so that would be Angela asked and then sometimes they use these lower letters to mark an angle as well so we could call this angle with a lowercase so you're the names at Conrad came up with the names of the angle r e f g e f g will that's one that we agree GES your sass de so that right there is not going to work because he didn't put the vertex in the middle the vertex is a beehive see in the mid so we're going to disagree with that answer and then angle ask you just using the vertex you are allowed to do that because of the angle so that one would be okay so we're going to say yes we agree with but if we were going to have all the right angles it would be these up here okay so we can say yes Angela EFG and angle for correct is wrong we already explained why it needs a vertex in the middle dance Tiffany's to do you want to and going to page 66066 deals with rotation that we worked on a couple of days how does a diagram it's labeled with points and letters and talks about going to read it as I can but it talks about somebody who has walking on this grid and making turns so for example you're a walking let's say the thing at the top of my 10 is the direction you're facing so this is like your face you're looking this way right now I'm walking towards point a I can stop at Point a and make one for turn to the right this way up for stern that's a 90° turn would have me facing the k then I could walk down to the K I could make a 1/4 turn where is walking where he at it's on the train said he makes so look at the diagram Palm walk from J to K Swiss to see where he starts he starts with j he's walking towards so he's walking towards chaos he's facing this way he's walking towards k2k he makes a 1/4 turn to the right kind of picture yourself looking in this direction which direction would be right it would be down this way now he's facing this way he makes a 1/4 turn to his right then he walked to 8 please turn to the right of course of a turn 90° he walks to DH there yes at that point he makes a half turn before walking to the end of that line so he gets here you spacing out this way he makes some tasks turn a house is 180 minute is it last right the house turn is going to end up in the same spot whether you turn a house to the last for you turn a house for the right way I can turn in this Direction that's a high or I can turn in this direction turn half a circle 180° either way I'm going to be pointing in this direction so he's at 8 he makes us past turn he's now facing this way here to stay that line is going to walk all the way to the end where will he be is that letter A all right if you wanted to kind of trace of house and starts with j he walks make 1/4 turn is a ride going down this way turn and head back up to the end of the line with r all right so that still works at 4 today you have suffered from work now and I mess up on the Clockwork homework and then you owe this page was in the past gas for practice you can cross it out if you want even though I took teenage sporting was optional I recommend that you do these angles on page 14 and in fact I'm going to do them with you if you want to cross out 13 you can do it if you want to but if you want to talk it out let's go ahead and turn to page 14 measure of each angle because this is what we're really focusing on right now and this has you practicing with the protractor and with naming the types of angles measure the angles below write the type of angle is less than 90° a right angle is exactly 90 degrees obtuse that's going to be greater than 90 less than 180 straight angle is exactly 180 and an anything greater than 180 is a reflex angle before you measure and say what type is this I can tell it's not a cute it's not small enough not a right angle doesn't look like the corner of a square it's not a straight line is smaller than a straight line n180 if I'm going to go ahead and right obtuse and then I'll line up the protractor to measure and you can put this on zero or you can put them spray on zero is up to you I'm going to put this right here on 0 which means I'm going to be using the interstate all so I'm lining up the vertex with the T there's Mighty mind that was quite and then I need to rotate the tractor are coming out at 000 is I'm going to follow the numbers all the way around and it looks like he gets to 103rd 131 remember that with these you can be a degree or two off and it's okay I think I'm going to put 130 degrees 529 130th hundred Thirty-One 132-133 does it all the correct answers because they're close enough for a small angle it's not open that much smaller than a right angle less than 90 degrees so we know that it's a cute before we even measure we're going to line up the protractor here's our her text the line up the key with the vertex Ray's coming out of zero there it is 0 and running use the outer scale because that's where my zero is and we don't make it to 30 less than 30 minutes top 20 past the halfway mark to I'm thinking maybe 20 2720 6727 within two degrees is can we have one more now this one when you look at it you can say okay I see the curve on the outside Martinez bigger angle so I know it's going to be a reflex angle do I need to measure a little differently we don't have a circle protractor Circle protractor with measure you could just put the zero here and it would go all the way around because we have a half circle what we do instead is we remember that circle is 360° if we went all the way around 360 so we're going to do is we're going to figure out the smaller angle and subtract that smaller angle from 36 outside of equal to we're going to measure the inside here even though that's not the Angela really trying to get that's going to help us get there Taylor Swift on the vertex that is my perfect is upside down if we have to do for the zero is right here the inner scale following the inner steel around it looks like it's about 75 degrees in here I'm not going to put that for my answer the angle I want I want this out or angle so I'm going to do 360 - 75 so that I know what the reflex angle is equal to and it looks like we have a reflex angle of 285 degrees so this was page 14 if you're following along you got it done now so you're done with classwork and homework like I said before page 13 my mistakes you can cross do you want to it's up to you
