GCSE Maths Practice: triangles-and-quadrilaterals

A rectangle is a quadrilateral with opposite sides equal and all angles equal to 90°. Unlike a square, not all sides are necessarily equal. Understanding rectangle properties is important for identifying shapes, calculating areas, perimeters, and solving geometric problems. Rectangles appear in diagrams, design layouts, and construction. Recognizing a rectangle requires checking that opposite sides are equal and angles are right angles. Practice comparing rectangles with squares, rhombuses, and trapeziums to reinforce understanding. Being familiar with rectangles helps in proofs, calculations, and real-world applications like architecture, engineering, and tiling. Mastery of these properties is essential for GCSE geometry.
