Use ΔABC shown below to answer the question that follows:

What statement is needed to prove that ΔABC is similar to ΔDBA?

A. Segment AD is an altitude of ΔABC.

B. Segment CB is a hypotenuse.

C. Segment CA is shorter than segment BA.

D. Angle C is congruent to itself.

I think it might be B but I'm bad at proofs so I'm not sure.

I can tell you A is wrong, B and C are probably irrelevant, so maybe D.

anonymous · Answer

D was wrong

campbell_st · Answer

If you prove AD is an altitude, then you have the right angle for triangle DBA and the  start of using Angle Angle Postulate... 

thats my best guess...

primeralph · Answer

I was going to say that, but AD does not look like an altitude with the given info.

well put Not to Scale on the diagram... covers all sins..
