Week #  20 

Unit of Instruction  5: Quadrilaterals and Coordinate Geometry 

Standard(s) Taught 

MAFS.912.GCO.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 

I can:
 prove and apply the properties of rectangles, rhombuses, and squares
 use the properties of rectangles, rhombuses, and squares to solve problems
 prove that a given quadrilateral is a rectangle, rhombus or square
 use properties of trapezoids to solve problems
 use properties of kites to solve problems
