# Which congruence test can be used to prove that triangle GHJ = triangle LKJ?

http://s3.amazonaws.com/answer-board-image/b9c59b7...

Its a bad picture but i didn't know how to explain it, in my textbook thats what it looks like but the triangles are congruent.

I think its SAS, but i don't know. Please help!

Update:

Which congruence test can be used to prove that Δ GHJ ≅ Δ LKJ?

since GH//KL [both are perpendicular to line GL]

<JKL=<JHG

<HGJ=90º=<JLK

Therefore the third angle is also equal, since the sum of the interior angles in a triangle =180º

given HJ=JK, both triangles are congruent. ASA
