Written by Adi Ackerman, Head Teacher

Two figures are congruent when a sequence of rigid motions maps one onto the other, and similar when the sequence also includes a dilation. There are 11 sheets for 8th grade here, each with an answer key. Sequences of Rigid Motions on the Coordinate Plane and Show Figures Are Similar With a Dilation and More work on grids, What Rigid Motions Preserve checks side lengths and angles, and two sheets use angle-angle similarity to test triangles and find missing sides. The sheets practice 8.G.A.1, 8.G.A.2, 8.G.A.4 and 8.G.A.5.
