Unit 6 Lesson 2 Properties of Parallelograms
Unit 6 Lesson 2: Properties of Parallelograms
Lesson Overview
Perpendicular Bisectors
What You Will Learn
- how to use relationships among sides and angles of parallelograms and its diagonals
Overview
In this lesson, you will learn how to use relationships among sides and angles of parallelograms and their diagonals. A parallelogram is a quadrilateral with both pairs of opposite sides parallel. In the Solve It (online textbook), you made some conjectures about the characteristics of a parallelogram. In this lesson, you will verify whether your conjectures are correct.
Essential Understanding
Parallelograms have unique properties regarding their sides, angles, and diagonals.
In a quadrilateral, opposite sides do not share a vertex, and opposite angles do not share a side.
