Outcomes

G-CO.11

Prove theorems about parallelograms. Theorems include: opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.

G-SRT.5

Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
