Classifying Quadrilaterals: Understanding Shapes and Properties
In this lesson, we will learn how to classify quadrilaterals based on their side lengths and angle measurements. A quadrilateral is defined as any four-sided polygon, which includes shapes like trapezoids, parallelograms, rectangles, rhombuses, and squares. We will explore the characteristics of each type: parallelograms have opposite sides that are parallel, trapezoids have only one pair of parallel sides, while rectangles, rhombuses, and squares have specific angle and side length properties. Engage in practice problems to reinforce your understanding before starting your homework.

Classifying Quadrilaterals (Day 1) Thursday, May 03, 2012 We are learning to…classify quadrilaterals based on their side lengths and angle measurements.
Vocabulary • Quadrilateral – Any four sided polygon • Examples: Trapezoid, Parallelogram, Rectangle, Rhombus, Square
Quadrilaterals Parallelograms Trapezoids A four sided polygon in which both pairs of opposite sides are parallel. A quadrilateral that has one pair of opposite sides that are parallel Rhombus Rectangle A parallelogram that has 4 congruent sides. A parallelogram that has 4 right angles. Square A parallelogram with 4 right angles and 4 congruent sides.
Quadrilateral Practice A square is a parallelogram that has 4 right angles which makes it a rectangle. True A parallelogram has two sets of parallel sides. A trapezoid has only one set of parallel sides. False A rectangle is a polygon with 4 sides which makes it a quadrilateral. True Try #4-10 on your own…raise your hand when you are done so you can start your homework assignment.
