Pentagon - Wikipedia
In geometry, a pentagon (from Greek πέντε (pente) 'five' and γωνία (gonia) 'angle' [1]) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting .

Jan 1, 2025 · Polygon geometry is a rich and compelling field exploring the complexity of two-dimensional shapes and their applications. Pentagons, hexagons, and dodecagons each have unique properties that lend them to various applications in art, science, and nature.
Polygons - Math is Fun
Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up). Polygon comes from Greek. Poly- means "many" and -gon means "angle". A regular polygon has all angles equal and all sides equal, otherwise it is irregular. A convex polygon has no angles pointing inwards.
