The Language of Geometry

Points identify a position. They are represented by dots. Ex) ∙B

Lines are made up of a set of points. A line goes on forever in both directions. Ex) <---C----D--->

A ray is a part of a line with one endpoint. A ray begins at the endpoint and goes on forever in one
direction. Ex) E-------------F---->

A line segment is part of a line with 2 endpoints. Ex) X--------------Y

An angle is formed by two rays or line segments with a common endpoint. The endpoint is called the vertex. The middle letter represents the vertex. Ex) L RSI
