So the question ask if the polygon ABCD rotates 70degree counterclockwise about point E to give polygon A'B'C'D' so which of the following among your choices is true about the the said polygon and the answer would be letter A. A'E = AE. I hope you are satisfied with my question 

Answer with explanation:

It is given that , when polygon ABCD is rotated by 70°in counterclockwise direction about point E to give polygon A'B'C'D'

When a Quadrilateral is rotated

1. The shape and size of two Quadrilateral do not change.

2. The Interior angle of two quadrilateral will also not change.

the Only relation ship which will be true is

Option C →m∠ABC=m∠A'B'C'

When we rotate a geometrical shape by a certain angle,it's interior angle do not change.
