Inscribing Regular 15-gon in Circle/Corollary

Corollary to Inscribing Regular 15-gon in Circle
In the same way as for the regular pentagon, we can draw tangents to the circle at the vertices of the regular 15-gon.

This will draw a regular 15-gon 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 15-gon and circumscribed about a regular 15-gon.

Proof
As described.
