Spirangle
A spirangle is a two-dimensional geometric shape that combines properties of spirals and angles. Specifically, a spirangle is a polygon where the vertices are positioned such that the angles between successive sides (interior or exterior angles) follow a spiral pattern, either increasing or decreasing in a consistent manner. This distinguishes it from regular polygons where angles are constant, and from irregular polygons where angles may vary randomly. The overall appearance of a spirangle tends to resemble a distorted or warped polygon that gradually curves inward or outward, depending on the nature of the spiral pattern defined by its angles. Spirangles are typically characterized by the number of sides they possess and the specific function that dictates the progression of their angles.
