Learning Objective

I can classify quadrilaterals.

Today's Lesson

Today we will learn how to classify quadrilaterals. Math helps us solve problems and understand the world around us.

A parallelogram is a quadrilateral with both pairs of opposite sides parallel. Properties: opposite sides are equal, opposite angles are equal, consecutive angles are supplementary, diagonals bisect each other. Rectangles, rhombi, and squares are special parallelograms with additional properties. These properties are used for proofs and finding missing measures!

Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!

Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.
