Question

In the diagram below, trapezoid ABCD maps to trapezoid A'B'C'D'.

Which angle corresponds to angle C'?

Answer 1

C is the Correct Answer

Explanation:

The answer above me ^^

Answer 2

Angle C corresponds to C'. First observe that C' is an obtuse angle, and only C or D in the first figure are obtuse angles. Then notice that D cannot be correspond to C' because it flips the left-right direction of the trapezoid. So C must be the correct answer.
