Intro to Rigid Transformations
Students learn to name, signal and perform translations, reflections and rotations without a grid.

More Transformations and Congruence Lessons
Transforming Coordinate Points
Students translate, reflect and rotate points, then discover and write the coordinate rule for each move.
Series of Transformations
Students name, describe and check a series of translations, reflections and rotations on the grid.
Corresponding Properties
Students match corresponding points, sides and angles, then use them to prove congruence and find missing measures.
Exploring and Proving Congruency
Students define congruent, spot congruent figures, and prove or disprove congruence with rigid motions.
How to Dilate an Image
Students dilate figures about the origin and from any center, then watch rays from the center check their work.
Sequences of Transformations
Students combine rigid motions with dilations, find a dilation's center and scale factor, and decide congruent or similar.
