Geometric Solids

A cone is similar to a pyramid as it has only one base and comes to a point. The difference between a pyramid and a cone is the base.  Cones have circular bases. Like other three-dimensional shapes discussed, there are right cones and oblique cones. The drawing on the left is a right cone and the one on the right is an oblique cone.

Right andOblique Cones

The net of a cone is drawn below.  It is not as obvious as the previous solids and you may want to explore this one by cutting open a party hat to see that it is indeed a sector of a circle.
