Answer 3

My eye sight is bad, What dose it say?

Answer 4

Sorry, it is kind of hard to read.

I have two triangles: triangleABC and triangle EHC

Both triangles are Right triangles.

Their angles are the same:
angleA is congruent to angleE
angleB is congruent to angleH
angleC = AngleC

I just need to write a two column proof to prove they are similar triangles

Answer 5

@SolomonZelman @ganeshie8 @SithsAndGiggles @TheSmartOne @mathslover @sammixboo Anyone?

Answer 6

Looks good! start by writing down the given info

Answer 7

1. angleA = 45 1. Given
2. angle E = 45 2. Given
3. angle A is congruent to angleE 3. Both angles have equal measures
4. angle B = 90 4. Given
5. anlge H = 90 5. Given
6. angleB is congruent to angleH 6. Both angles have equal measures
7. ?? 7. ??

Answer 8

I've actually never written a two column proof as crazy as it may seem.

7. TriangleABC is congruent to EHC 7. AA?

Answer 9

Yes! but you want to prove they are similar right ?

Answer 10

7. TriangleABC is `similar` to EHC 7. AA similarity

Answer 11

you're done!
