Understanding Quadrilaterals and Their Properties

This lesson covers the classification of quadrilaterals, including trapezoids, rectangles, squares, and rhombuses. It explains the defining characteristics of each shape, such as parallel sides and right angles, and provides exercises to practice identifying these shapes. The lesson emphasizes understanding the differences between similar shapes and encourages practice to master the concepts.
