Increase the number of sides of the polygon to see it approximate the unit circle. As the number of sides increases, the area of the polygon approximates the area of a circle with increasing accuracy, showing that the value of π can be estimated with regular polygons. ...

Inscribed Polygon: A polygon is inscribed in a circle if and only if each of its vertices lie on the circle. ... Triangle ABC, quadrilateral DEGF, and pentagon HIJKL are each inscribed in a circle. Notice for each inscribed polygon, all the vertices lie on the circle and the polygon lies entirely inside the circle.

A regular 18-sided polygon is inscribed in a circle, and triangles are formed by joining any 3 of the 18 vertices. How many obtuse triangles are there? ... You can also see it by remembering that any angle inscribed in a semicircle is a right angle. Now, if the arc from A to C through B is less than a semicircle,
