In this lesson, we will learn how to determine whether a quadrilateral is a parallelogram or not and use the properties of parallelograms to find unknown angles or lengths.

Lesson Plan

Students will be able to

recognize the following properties of a parallelogram:
- opposite sides are parallel,
- opposite sides are equal in length,
- opposite angles are equal in measure,
- the sum of two adjacent angles is ,
- the diagonals bisect each other,
identify the following special cases of a parallelogram:
- rectangles,
- rhombuses,
- squares,
classify quadrilaterals,
use the properties of quadrilaterals to find missing lengths and angles in geometric figures.
