okra77 · Answer

what you got always start with the given and use definitions

anonymous · Answer

I have the givens down I just have trouble proving how the triangles are congruent

okra77 · Answer

can you put the problem up triangles are proved congruent by sas sss or asa

solomonzelman · Answer

yes, and you can still prove that they are proportional if you have AAA.

okra77 · Answer

i think that would be similar triangles

anonymous · Answer

My class just learned about ASA i don't get how to put it into use

okra77 · Answer

if you show that one pair of angles is congruent then a pair of sides  congruent then another pair of sides congruent then u have asa the sides have to be between those two angles though

anonymous · Answer

Ok so its not congruent if it goes angle angle side

okra77 · Answer

no that is similar for instance two triangles could have the same angle measures but one be much larger than the other

anonymous · Answer

ok now I get it
