This animation introduces polygons as closed two-dimensional shapes made of straight line segments. It visually distinguishes regular from irregular polygons, names shapes by their number of sides (triangle through decagon), and classifies them as convex or concave. Interior angle sums are demonstrated by splitting polygons into triangles. Designed for GCSE and IGCSE Edexcel maths students, it builds the foundational vocabulary and visual recognition needed before tackling angle-sum formulas and polygon-related exam questions.
