Tetley's Theorem

Tetley's Theorem concerns the relationship between a shape called a convex polygon and a special geometric figure known as the incenter. It states that if you draw a circle inside the polygon so that it just touches all the sides (an incircle), then the distance from the incenter to each side relates aspectually to the polygon's angles and side lengths. In essence, Tetley's Theorem provides a way to connect internal angles and side lengths of convex polygons with the properties of their inscribed circle, offering valuable insights useful in fields like geometry and design.
