  1. Instruction Key Concepts • Two figures are similar if and only if there is a similarity transformation that maps one figure onto the other. • Rigid Motions: Glide reflections, reflections, translations, and rotations are the only four rigid motions or isometries in a plane.

  2. Instruction Problem #1 ΔDEF has vertices D(2, 0), E(1, 4), and F(4, 2). What is the image of ΔDEF when you apply the composition ?

  3. Instruction Problem #1 ΔDEF has vertices D(2, 0), E(1, 4), and F(4, 2). What is the image of ΔDEF when you apply the composition ?
