Details on the full 66-page unit with direct TPT link 🎯 CCSS STANDARDS ADDRESSED

8.G.A.3 — Describe the effect of dilations on two-dimensional figures using coordinates 8.G.A.4 — Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations 8.G.A.5 — Use informal arguments to establish facts about the angle-angle criterion for similarity of triangles ❤️ PERFECT FOR
