Question

Name the postulate or theorem you can use to prove the triangles congruent.

Answer 1

If you want help, my friend, then you might consider typing up the information relevant to enable me to help you. What triangles? How are they congruent? Let's get some figures here!

Answer 2

ASA Postulate
AAS Theorem
SAS Postulate
HL Theorem

Answer 3

I'm not an expert on geometry, so double-check this for sure, but my gut feel goes with SAS Postulate, since you're given that the two opposite corresponding sides are congruent, the right angles obviously are equal and congruent, and the triangles share a side, making it congruent. Two sides and an angle.

Answer 4

thank you

Answer 6

you see they have the same hypotenuses and they have the same leg length, so the other leg must be equal according to the pythagorean theorem, so maybe HL postulate, could mean 'Hyopotenuse Leg' Postulate

Answer 7

Theorem

Answer 8

Dan is correct, again it has been quite some time since I've done hands-on geometric proofs, my apologies for misleading.
