# Geometric Construction

A geometric construction is a construction of a geometric figure using only straightedge and compass, as originally studied by the ancient Greeks.

Geometric construction is an elementary-school-level concept. It is listed in the California State Standards for Grade 5.

### Prerequisites

Circle: | A circle is the set of points in a plane that are equidistant from a given center point. |

Geometry: | Geometry is the branch of mathematics that studies figures, objects, and their relationships to each other. This contrasts with algebra, which studies numerical quantities and attempts to solve equations. |

Line: | A line is the infinite extension in both directions of a line segment, giving the path of shortest distance between two points in Euclidean space. |
