What Are Solid Figures?

A three-dimensional object that takes up space

A two-dimensional surface/side in a solid figure which is flat

A two-dimensional surface/side in a solid figure which is curved

Polyhedron where three or more triangle-shaped faces meet at a top point above the base

A straight line segment, which bounds a surface

A smooth-flowing line, which bounds a surface

A three-dimensional figure with two identical faces at the top and bottom, often called bases. In addition, all the figure’s other faces are flat.

A three-dimensional figure with two identical circular faces at the top and bottom, often called the bases. The bases are connected by a curved surface.

A three-dimensional figure with a circular base and a pointed curved surface

A closed surface. All plane cross sections are either ellipses or circles.

A special case of an ellipsoid. All the surface points have the same distance from a common point.
