Question

Fan and Medal:
How would I determine and/or show that an angle is congruent to its corresponding angle. Original triangle coordinates W(-2,-3) G(6,-3) C(6,3). The second triangle coordinates W(-3,2) G(-3,6) C(3,-6).

Answer 1

ew its ash no one help her

Answer 2

Sam you suck.

Answer 3

im only joking but i dont know the answer

Answer 6

You're pretty hot. I guess I'll just fan and medal you.

Answer 7

you already fan me ;D

Answer 8

Yeah I know. xD

Answer 9

Sounds like fun math^!!! "You're pretty hot. I guess I'll just fan and medal you."

Answer 10

No one knows this answer. So might as well.

Answer 11

do you know about the law of cosines?

Answer 12

actually here's a better way. all you need to do is solve for the distance between all the points in each shaped (aka solve for the lengths of each of the sides of the triangle). Then set up a ratio stating for example that WG1/WG2 = WC1/WC2. If all of these are of the same ratio, then the triangles are atleast similar. And when two triangles are similar they have congruent angles right?

Answer 13

Yes completely. Theres this assignment I have and ive completed everything but the last part where it states To show an angle is congruent to a corresponding angle, you can use slope or your compass and straightedge. (Hint: Remember when you learned how to copy an angle?) You must show all work with the distance formula for the corresponding pair of sides and your work for the corresponding angles to receive full credit

Answer 15

sorry for the late response! is this a different problem?

Answer 16

or part of the same problem?

Answer 17

No you're good. Actually I had a whole assignment. I completed everything except the part where I am supposed to demonstrate and show my angles are congruent.

Answer 18

Ahhh ok so do you have question/problem with my explanation of how you go about proving it? (I would implement the method of copying an angle using a straight edge and compass into my explanation however, it's been years (about 10) since I did geometry and alas I have forgotten how to do so).

Answer 19

Oh ok. Well as far as showing my angles are congruent using a compass and a straight edge. I would do so by just marking my point of intersection?

Answer 20

I don't know, I will have to take your word on it lol.

Answer 21

Thank you so much. I was just confused because I can see showing both angles are congruent if they were in the same placement because then the point of intersection would lie on the same point. But this particular assignment demonstrates a rotation where each triangle coordinate lie on a different point.

Answer 22

ahh I think i see? Anyways yeah all you need to do is prove that they are similar aka the ratio of their respective sides are the same. That proves angle congruence.

Answer 23

Ok so as far as slope goes. I just determine the slope for each of the 3 corresponding points, and show that each corresponding point has the same slope?

Answer 24

no you don't care about the slope all you care about is the distance between each point.
