Question 4

Which diagram can be used to prove △ABC ~ △DEC using similarity transformations?

Revolt · Accepted Answer

Triangle A B C is rotated about point C and then is dilated to form smaller triangle C E D.

Question 5

Read the proof.Given: AEEC; BDDCProve: △AEC ~ △BDC

Revolt · Accepted Answer

∠ACE ≅ ∠BCD
