A bicentric polygon is a type of polygon that possesses both a circumcircle and an incircle. A circumcircle is a circle that passes through all the vertices of the polygon, while an incircle is a circle that is tangent to each side of the polygon. For a polygon to be classified as bicentric, it must meet specific criteria: 1. **Circumcircle**: All the vertices of the polygon lie on a single circle.
