2 Lesson Objectives Standards Lesson Notes G.MG.1 Use geometric shapes, their measures, and their properties to describe objects. G.GPE.4 Use coordinates to prove simple geometric theorems algebraically. G.GPE.5 Prove the slope criteria for parallel and perpendicular lines and use them to solve geometric problems (e.g., find the equation of a line parallel or perpendicular to a given line that passes through a given point). G.CO.11 G.CO.12 Prove theorems about parallelograms. Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.). Parallelogram A quadrilateral in which both pairs of opposite sides are parallel Parallelogram A quadrilateral in which both pairs of opposite sides are parallel Cut this piece off Parallelogram A quadrilateral in which both pairs of opposite sides are parallel Cut this piece off Opposite sides are congruent. Consecutive angles are supplementary Opposite angles are congruent. Diagonals bisect each other. 2. 8x If a parallelogram has 1 rt 's, then it has 4 rt angles.
