Question

imagine that the rectangle is rotated counterclockwise. make a conjecture as to which properties of a figure stay the same after the rotation. vertices sides angles lengths shape size

Explanation:

A rotation is a rigid - motion transformation. Rigid - motion transformations preserve side lengths, angle measures, shape, and size. The vertices change their position in the coordinate plane. The sides and angles remain the same in terms of their measure, the lengths of the sides don't change, the shape remains a rectangle, and the size (area and perimeter) doesn't change.

Answer:

sides, angles, lengths, shape, size
