A shape that has four sides is called a quadrilateral. Quadrilaterals can come in various forms, including squares, rectangles, trapezoids, and rhombuses.
Each of these shapes has its unique properties, but they all share the common characteristic of having four sides. For example, a square has equal sides and all right angles, while a rectangle has opposite sides that are equal in length and also features right angles. Understanding these different quadrilaterals helps in recognizing various shapes we encounter in everyday life.
