@ganeshie8 @hartnn @phi Please help, this is my last question of my last assignment for flvs forever.

OpenStudy (anonymous):

You know that both m<ACE and m<BCD are made from adding m<ACD + m<DCE. What does this mean about the two angles? It uses a certain property that starts with a T. Think: If 1+2=x and 1+2=y, it means that x=y.

tra..

OpenStudy (anonymous):

I have this right now but I don't think it is correct ..... A. ACE = BCD because of substitution B. The proof would not work without the missing step because ASA depends on two angles

OpenStudy (anonymous):

A is correct, except for the reason. Substitution technically works, but there's a better answer. It starts with "tran..." B is correct.

OpenStudy (anonymous):

Transitive?

OpenStudy (anonymous):

Yes, the transitive property. If A=B and B=C, then A=C. That's all it's saying. Your answers should be correct now.

So my second answer is correct? Is it complete or is it missing a part?
