alright this says in a kite the measures of the angles are 3 x 75 90 and 120 find the IMAX what are the measures of the angles that are congruent so actually going to start this one off the same way that we did the last problem so first find them some of the cheer angles I'll give you a hint it's going to be the same since we're still doing still dealing with tights so just in case 4-2 what time is 184 - 2 - 2 * 180 360  now we're going to add up all the angle measures that are given to us instead of equal to 60  so 3x + 75 + 90 + 120 equals 360 I need my calculator again 20 + 90 + 75 285 what's 3x + 285 equals 360 so - 3 6-2 85 from both sides I need 75 so 3 x equals 75 divided by 3 divided by 3x equals 25 but we are not done cuz it says what are the measure of the angles that are congruent so I need to plug it back in to find this missing 3 * 25 is 75 so the angles that are congruent are 75 because they show up twice in Arles the congruent angles where are  75 degrees  two days composite if you need to catch otherwise I'm going to keep caught  oh I kind of cut it off on my picture no no no this is just a little flowchart for you guys on what where each figure that we've talked about Has Fallen are all types of quadrilaterals that we talked about so far because they all have four sides so the only requirement of a quadrilateral is that it has four sides and then we've got parallelograms over on the left hand side and a parallelogram can be either a rectangle rhombus or a square but then remember like a I like to think of a square as a rectangle and rhombus had a baby and they named it Square so squares got a little bit of rectangle and a little bit of rhombus and then another type of quadrilateral is a trapezoid and underneath the trapezoid art of the trapezoid family is an isosceles trapezoid  and then last but not least is a kite like I said hopefully tomorrow will be able to do kind of organized these in a way that makes a little bit more sense or just so that's just like all in one area so you not to keep trying to look for it and all your notes example sticks identifying a quadrilateral what is the most specific name for quadrilateral ABC alright well I'm looking at this I only know this part right here  that are diagonals  when it cut something into two equal pieces what does that called raise these cuz I don't like the way they are. You can see them what is it called when the diagonals hit each other into equal spots hopefully you guys are saying midpoint maybe middle but really bisects is the word that I am thinking of and that's the only information can I know so I can't say that it's a square even though it looks like a square can't say that it's a rectangle even though it looks like it's a rectangle I can't say it's a rhombus I can't say any of those things so the most specific name I can give it is a parallelogram what is the scariest looking anyways because the diagonals bisect each other so that's all we can say because it doesn't give us any right angles it doesn't tell set the whole lines are congruent no other information so we can only say that is a parallelogram because the diagonals bisect each other the last one is a monitoring progress I want you and your partner to try and figure it out first before you guys open up the next video
