Rotating a geometric shape around a line within its geometric plane as an axis results in a solid of revolution.
The conic section is a plane curve that is created when a right circular cone is intersected by a plane.
This animation demonstrates various types of cylindrical solids as well as their lateral surfaces.
This animation demonstrates geometric rotation, a type of geometric transformation both in plane and space.
Rotating a rectangle around its axes of symmetry or around its sides results in solids of revolution.
This animation demonstrates various groups of solids through examples.
A sphere is the set of points which are all within the same distance from a given point in space.
