Unfolding Trucated Hexagonal Pyramid

Today I will introduce a geometric construction by using Cabri 3D. Cabri 3D is a program to make 3 dimensional geometric constructions.

     

There are two links below. One of them is Dropbox link of the document which includes unfolded truncated hexagonal pyramid. The other one is YouTube link of construction video of this pyramid.
