Inscribing Regular Hexagon in Circle/Porism

Porism to Inscribing Regular Hexagon in Circle
The side of a regular hexagon equals the radius of a circle which circumscribes it.

Proof
In the same way as for the regular pentagon, we can draw tangents to the circle at the vertices of the regular hexagon.

This will draw a regular hexagon which has been circumscribed about the circle.

Further, in a similar way to methods used for the regular pentagon, a circle can be inscribed in a regular hexagon and circumscribed about a regular hexagon.
