GCSE Maths Practice: triangles-and-quadrilaterals

A regular polygon has all sides equal in length and all interior angles equal. A square is a classic example of a regular polygon with four equal sides and four 90° angles. Understanding regular polygons helps in identifying shapes, calculating angles, and solving geometric problems. Squares appear frequently in diagrams, tiling, and real-world objects such as windows and tiles. Recognizing a square among quadrilaterals requires checking that all sides are equal and all angles are right angles. Practice drawing squares, labeling sides and angles, and comparing with rectangles, rhombuses, and trapeziums to reinforce understanding. Familiarity with regular polygons is important for GCSE geometry, proofs, and real-world design applications.
