Content Standards G. CO. 6 Use geometric descriptions of rigid motions to transform figures and to predict the effect of a given rigid motion on a given figure; given two figures, use the definition of congruence in terms of rigid motions to decide if they are congruent. G. CO. 7 Use the definition of congruence in terms of rigid motions to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent. Mathematical Practices 1 Make sense of problems and persevere in solving them. 7 Look for and make use of structure.

Verify Congruence after a Transformation Triangle PQR with vertices P(4, 2), Q(3, – 3),

Verify Congruence after a Transformation Triangle PQR with vertices P(4, 2), Q(3, – 3), and R(5, – 2) is a transformation of ΔJKL with vertices J(– 2, 0), K(– 3, – 5), and L(– 1, – 4). Graph the original figure and its image. Identify the transformation and verify that it is a congruence transformation.
