hey good morning this is Tuesday's workbook pages so today for Matthew have Pages 58 and 59 in your workbook and if you work all day yesterday we were on turns and turns related to angle so we did this page and remember we talked about Kyle of fourth of a turn is equal to 90 degrees or 1/4 of a way around a circle would be 90° and so then halfway around a hundred degrees so it says look at the three pairs of angles driftstone so the angles more open than a right angle to a greater than 90 but it's not all the way to a straight line so it's less than 180 days you look at seeing a look at where the curve is so inside outside it goes all the way past the straight line straight line would be right here so it's more than 180 but it doesn't make it three quarters of the way it's not to 76 greater than 180 looks like it's probably meant to be just a straight line 180 degrees so it says which pair of angles trips so a half turn halfway around a circle this one is a hundred degrees that would be halfway around a straight angle is 180 degrees turn turn and a 3/4 turn so I have to remove the 180 has turned 180 degrees turn remember every fourth is 90 + 90 + 90 + 90 + 2 add up to 270 degrees looking for an angle that's greater than 180 72 which of these has something greater than 180 and 270 three pairs of angles driftstone so same idea but different angle you look at the two strips on top of each other all the way around and come back to the begin Circle 360 Degrees e k it is past that right angle past 9 but it doesn't make it all the way to a straight line it's not a hundred eighty so it's greater than 90 but less than 180 almost as big as D but not twice it's like a star just here went past 90 went past 180 went top to set quite make it all the way around which pair of angles strips shows 360 Degrees about the full circle turn that's going to be letter and which one does an angle between 180 and 360 the greater than 180 means it's been past the straight-line this one is not made it past the straight line and it has to be less 360 so I can see this one it's going to be better 180° makes up blank of a full turn to a pool party 360 180. The straight angle or it is halfway around the circle so it's half turn three right angles make up a boy trying to remember we said a right-angled up to 90 degrees 90 degrees is equal to 1/4 of a circle but if you have three right angles and that's going to be one-fourth plus one-fourth three right angles 270 degrees is going to be equal to 3/4 of a turn 105 degrees is between a blank turn and a blank turn and I think they want us using fourth or have their holes not other fraction self 105 degrees that's half 90° turn but it's not all the way to a hundred eighty degrees PS4 stand 5959 Holiday Circle full circle protractor free to look at full circle pro tractors are useful I sometimes prefer to use them although we generally use half circle protractor is in the process because that's what you the most classes we want to learn how to use it 360° so this one if you looks like zero is right here is coming out at the bureau if you follow the number counting by tens 20-30 it doesn't quite make it all the way to 40 looks like it's past 35 though by 2° so we would say that this angle is 30 37 degrees 37° just using the circle protractor instead of the is the measure of angle X or Y so what fraction of the circle does that angle cover so we know it's a 37 degree angle and when we make a fraction card over the phone so we have 37 degrees out of how many is the question so how many degrees they got the whole circle and if you look at it again or if you just remember a circle is equal to 306 so we would say that this angle covers 37 out of 360 Degrees that's the facts and the covers all right so that's the end of your workbooks for today you have some proper homework you have paid 9 that is required and taste 10 that is optional I'm going to get that started with you this is Peyton I find some practice measuring angles and we're going to start with this one the measure of angle LMN be so that's the same goal here and then the type of angle we're going to write what type is now if you look at the curb here you can see that the angles find the measure for is on the outside here is that reflex angle that big angle greater than 180 remember because we're using a half circle protractor the way that we find the measure of a reflex angle find the measure of the smaller angle to get the measure of the outside part so before I even measure I do know what time what part is greater than 180 the reflex angle and now to find the measure I'm going to measure the inside angle so I'm going to have the protractor lineup right here on the vertex I'm going to line up this side with 00 following the outer scale around until I get to the second Ray remember it's okay to be a degree or two off I'm getting about 40 play about 43 degrees for this so I'm going to write that in here just so I don't forget it that's not the answer navigate to the outside angle that I actually inside parts of the 43 317 degrees so that's our answer for this one 317 is a reflex angle start to save yourself what kind of angle am I looking at a smaller than a right angle is acute obtuse or right angle would look kind of like this it's bigger than that but it doesn't make all the way to a straight line straight angle or reflex it's between 90 and 180 so we say it's obtuse say and we're going to line up the protractor to measure it here vertex bounty on the vertex and then a rotation so it's lined up with 0 using the outer scale again following it around it looks like this Ray comes out at about I'm getting like one 3939 remember you can be a degree or two above or below. In correct on a test 139 obtuse angle so this is going to be an angle that is smaller than a right angle so it's going to be and you're going to light it up like this and get the measurement let you try that one on your own and then you have one more down here and this is another reflex angle I'm going to do this one with you this if you need a little more that means your answer when you do do it should be less than 90 but here we are on our reflex we get picture of a reflex angle remember we need to measure the inside part and then do 360 - that measure so that they get the measure of the bigger angle when I go ahead in line at the protractor I hear the Rays coming out at 0 follow the outer scale looking like it's about Avenue or so how to get the outside parts of reflex amenity 360 - 72 and that'll tell me the answer that I want this outer ankle so we end up with 288° so you want to measure here on your own remember it's an acute angle so you should get something less than 90 and then optional if you want to do it is can we have some rounding and then just writing some types of angles you don't have to actually measure anything to say what type it is
