Rotation

Understanding rotation of shapes and preserved properties. Drawing the transformed shapes using interactive tools.

Mapped to CCSS Section# 8.G.A.1, HSG.CO.A.2, HSG.CO.A.3

Verify experimentally the properties of rotations, reflections, and translations. Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch). Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.
