What is a Quadrilateral?
A quadrilateral is a polygon with four edges (sides) and four vertices (corners). Examples include squares, rectangles, and trapezoids. Understanding these shapes is fundamental to geometry and they are used in various real-life applications. Let's delve into some common types of quadrilaterals:
- Square: All four sides are of equal length and all angles are 90 degrees.
- Rectangle: Opposite sides are equal and all angles are 90 degrees.
- Trapezoid: Only one pair of sides is parallel.
