Introduction
Rotations are a rigid motion that focus on turning an object. The object maintains its shape, meaning it has the same line and angle measures.
Task
Your job is to create a triangle and rotate it clockwise 90 degrees, 180 degrees, and 270 degrees. Draw them on grid paper.
Process
You will need graph paper and a writing utensil. It would be preferable if there are no coordinates on the origin, aside from that your triangle is completely customizable.
