Properties of Quadrilaterals

The video tutorial explains the classification of quadrilaterals based on their sides and angles. It introduces the concept of quadrilaterals, which are four-sided polygons, and describes how they are named according to specific properties. If all sides are equal, the shape is a rhombus; if all angles are 90 degrees, it's a rectangle. A square has both equal sides and angles. Quadrilaterals are also classified by parallel sides: a trapezoid has one pair of parallel sides, while a parallelogram has two. The tutorial emphasizes using the most specific name for each shape.
