Regular polygon

A regular polygon is a flat shape with straight sides that are all the same length and angles that are all equal. Think of it as a perfectly symmetrical shape where each corner (vertex) and each side are identical. Examples include an equilateral triangle, a square, or a regular pentagon. These shapes are often used in design, architecture, and math because of their symmetry and uniformity. The key features are equal sides and equal interior angles, making them predictable and balanced in appearance.
