Question

An irregular parallelogram rotates 360° about the midpoint of its diagonal. How many times does the image of the parallelogram coincide with its preimage during the rotation

Answer 1

2

Explanation:

A parallelogram is 4 sided figure. Since it is a irregular, the sides and angles must be in different measures.

When we rotating the irregular parallelograms about the midpoint of its diagonal, it will coincide with its pre-image at 180 degrees and 360 degrees.

Therefore, the answer is 2.
