Introduction

Rigid motions are transformations that move a figure without changing its size or shape. Common rigid motions include translations, rotations, and reflections. Some...

Jordan was given two congruent parallelograms, ABCD and PQRS, on a coordinate plane.

He wanted to find a sequence of rigid motions that would map parallelogram ABCD onto parallelogram PQRS.

A good strategy is to match the orientation first. So, he rotated parallelogram ABCD by 90 degrees counterclockwise about the origin.
