Question

If polygon ABCD rotates 70° counterclockwise about point E to give polygon A'B'C'D', which relationship must be true?

A.
BB' = DD'
B.
m∠ABC > m∠A'B'C'
C.
A'E' = AE
D.
m∠ABC < m∠A'B'C'

Answer 1

C. m∠ABC=m∠ABC

Explanation:

A polygon stands as a two-dimensional geometric formation that contains a finite number of sides. It is shown that when polygon ABCD exists rotated by 70°in a counterclockwise order about point E to present polygon A'B'C'D'. so C. is your answer
