Strand: Measurement and Geometry
The student will identify and draw representations of points, lines, line segments, rays, and angles.
Understanding the Standard
A point is an exact location in space. It has no length, width, or height.
A line is a collection of points extending indefinitely in both directions. It has no endpoints.
A line segment is part of a line. It has two endpoints and includes all the points between and
including those endpoints.
A ray is part of a line. It has one endpoint and extends indefinitely in one direction.
An angle is formed by two rays that share a common endpoint called the vertex. Angles are found
wherever lines or line segments intersect.
Geometric notation to name lines, line segments and rays is included in grade four.
