This interactive exercise looks at angles of rotation and rotational symmetry of a variety of figures.

This task uses GeoGebra software, which can be freely downloaded, to explore what happens to the line segments and angles of a triangle when it is reflected, rotated, and translated. Includes printable task sheet for students and a...

The goal of this task is to encourage students to be precise in their use of language when making mathematical definitions. After working on this problem, they are asked to give a proper definition of a rotation by an angle about a...

Given a figure on the coordinate plane and a center of a rotation, find the angle for the rotation that maps one figure to the other.
