# Geometric figures

A geometric figure is any combination of points, lines, or planes.

### space figure

A space figure is a three-dimensional geometric figure, or a figure that occupies space and has volume.

Example

The tent shown below is in the shape of a triangular prism. The drawing depicts the three dimensions of a triangular prism.

### plane figure

A plane figure is a two-dimensional geometric figure.It has no thickness and lies entirely in one plane.

Example

The triangular prism shown below has plane figures for faces. Two of these faces are triangles.

### lines, line segments, and rays

Lines, line segments, and rays are one-dimensional geometric figures.

Example

The base of this triangle is a line segment. It has one dimension, length:

### points

In the triangle above, the vertices are labeled A, B, and C. These points could be called zero-dimensional geometric figures because they do not occupy space.

Also called geometric shape.
