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.
