Exploring Properties and Calculations of Quadrilaterals

This video tutorial covers various types of quadrilaterals, including squares, rectangles, rhombuses, kites, parallelograms, and trapezoids. It explains their properties, such as congruent sides and angles, and provides formulas for calculating area and perimeter. The video also includes practice problems to reinforce understanding.
