Question

Choose the letter of the correct answer (Complete the congruence statement)

A. AFED
B. ADEF
C. AEDF
D. AEFD
E. ADFE

Answer 1

D

Explanation:

when flipping and turning the second triangle, so that it is oriented as the first triangle (we see DE corresponds to AB - consider at what corner point the right angle is : at A and at D; DF corresponds to AC, EF corresponds to BC), we see immediately that BCA is the same sequence of corners as the corresponding EFD.
