What is a pendedecagon?
A pendedecagon, also known as a pentadecagon, is a polygon with 15 sides and 15 vertices. The term is derived from the Greek prefix "penta-" meaning five and "deca-" meaning ten, together indicating fifteen. In geometric terms, a regular pentadecagon has equal sides and angles, and its interior angles sum up to 2340 degrees.

A full rotation = 360°; a right angle = 90° → there are 360° ÷ 90° = 4 right angles in a full turn.
What does a pentadecagon look like?
In geometry, a pentadecagon (or pentakaidecagon) is any 15-sided, 15-angled, polygon. A regular pentadecagon has interior angles of 156°, and with a side length a, has an area given by: A= 15/4 * a²* cot π/15 = (15a²)/8 (√3 + √15+ √2* √(5+√5)) ≈ 17.6424 a²
