Best ResponseYou've already chosen the best response.0I think its BH congruent to CH and BG to CL. I could be wrong because I never did this before....... ;)

Best ResponseYou've already chosen the best response.0@e.mccormick So, what do you think?

Best ResponseYou've already chosen the best response.1AAA all three angles congruent only proves similarity, not congruance. dw:1434063901941:dw

Best ResponseYou've already chosen the best response.0Yeah, I know that. The same goes for SSS, ASA, SAS, and AAS right?

Best ResponseYou've already chosen the best response.1You always need to go with all three sides, anglesideangle, or sideangleside to prove congruence.

Best ResponseYou've already chosen the best response.1AAS... f I recall, does not always come out congruent.

Best ResponseYou've already chosen the best response.1There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL. http://www.mathsisfun.com/geometry/trianglescongruentfinding.html

Best ResponseYou've already chosen the best response.0I'm leaning a little closer to D.

Best ResponseYou've already chosen the best response.1Well, they only gibe two sides, so you must use an angle out of the image that must be the same... which means that the rules for angles on crossed lines need to apply.

Best ResponseYou've already chosen the best response.1Note it is AAS that is congruent, not SSA.

Best ResponseYou've already chosen the best response.1That was the one I was trying to remember that tricks people... SSA.

Best ResponseYou've already chosen the best response.1Take this triangle with the marked side, side and angle: dw:1434064547599:dw

Best ResponseYou've already chosen the best response.1Now, let me modify it so those are the same, but the triangle is not: dw:1434064605461:dw If done carefully or with a compass, this can show that SSA/retricetriangles do not prove congruance.

Best ResponseYou've already chosen the best response.1Because the radius of the sircle determines one side, a circle can prove that retricemakes for two triangles... That was the proof I was trhying to think of.

Best ResponseYou've already chosen the best response.1Anyhow... one of those answers you liked was retrice not SAS.

Best ResponseYou've already chosen the best response.1It will never be angles alone. That was the AAA problem. So you need sides. So it was one of the side ones, as you thought. So which side answer is SAS and which is SSA?
