A square based pyramid is a pentahedron, meaning it has five faces. It consists of four equilateral triangles, which have equal sides and equal angles. This shape is a regular polygon, which by definition has a regular polygon as its base and equally sized triangles as its faces. An irregu...
A right pyramid having a square base is inscribed in a sphere of radius R, all five vertices of the pyramid lying on the sphere. The height of the pyramid is x; show that the four vertices forming the base of the pyramid lie on a circle of radius r, where r^2=2Rx-x^2. Hence,...
