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

Answer:

2.

Step-by-step explanation:

Rotating a figure about the midpoint of its diagonal, the figure will coincide with its pre-image two times: at 180° and at 360°.

This is different than rotating about the origin; for a rotation about the origin, a 180° rotation does not always coincide with the pre-image.

hope that answers ur question :))))
