Teacher Felicia Taylor Geometry Honors 8th 19 5: Quadrilaterals and Coordinate Geometry
Standard(s) Taught

MAFS.912.G-CO.3.11

Prove theorems about parallelograms; use theorems about parallelograms to solve problems. (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.)

Learning Targets and Learning Criteria

Students will:

• Be able to classify polygons based on their sides and angles
• Be able to find the interior angles measure of a polygon
• Be able to find the exterior angles measure of a polygon
• Be able to identify the properties of parallelograms
• Be able to use properties of parallelograms to solve problems
• Be able to prove that a given quadrilateral is a parallelogram
