Explore the role of reflection symmetry in the Common Core State Standards. Use reflections to help students gain insight into the attributes of figures and to prove seven theorems in G-CO.8, 9, 10, 11: points on the perpendicular bisector of a line segment, base angles in an isosceles triangle, diagonals of a rectangle, and criteria for triangle congruence.
