Quadrilaterals and Their Properties

The video tutorial covers the classification of quadrilaterals, focusing on parallelograms, rectangles, rhombuses, and squares. It explains how to use the distance formula to determine if sides and diagonals are congruent, which helps in classifying the shape. The tutorial includes a detailed example using coordinates to demonstrate the process of identifying a rectangle by checking the congruency of sides and diagonals.
