Twisted Pyramid
Twisted Pyramid
A regular pyramid is the result of connecting a regular polygon with an apex point directly above the center of the polygon. If you twist a regular pyramid, its lateral faces are no longer triangles but curved surfaces.
This Demonstration shows the effect of axial twisting on the edges and lateral faces of a regular pyramid. A section between the polygonal base and the apex shows the twisted edges and offers an inside view into the twisted pyramid.
