What is a cone?
Notice some important facts about a cone:
1. It has a flat base
2. It has a curved surface , so it is not a polyhedron
Let's drag the following cone so as to view it at different angles. (You can click the button - 'drag' to stop the cone moving and click the button again to resume it moving.)
