Students can review basic geometric terms using these self-check, multiple choice questions. Three levels of questions are provided.

A list of geometry definitions and a matching activity.

Explains the terms and symbols used to discuss line angles, what an angle is, and the types of angles. Includes short video lesson demonstrating how to use a protractor to measure an angle. [0:57]

In this seven-problem quiz/practice students calculate the point at which a ray intersects with a plane in three dimensions.

Draw rays, lines, and line segments with given points.

In this lesson, students use line segments, angles, and parallel and perpendicular lines in order to create a one point perspective drawing.

[Free Registration/Login Required] In this lesson the teacher will use geometry and spatial sense to distinguish between point, ray, line, line segment and angle. The students will review vocabulary for these terms and then...

The tutorial examines basic geometry vocabulary. Definitions and examples of a point, line, line segment, ray, and plane are included.

This lesson focuses on Euclidean Geometry terminology; such as line, point, line segment, congruence, circle, radius, ray, and more. It defines each term and provides an example of each.

[Free Registration/Login may be required to access all resource tools.] In this lesson students identify points, rays, lines, and line segments. Students examine guided notes, review guided practice, watch instructional videos and...

[Free Registration/Login may be required to access all resource tools.] In this lesson students define and use geometric terms. Students examine guided notes, review guided practice, watch instructional videos and attempt practice problems.

Provides examples and a video lesson that introduce fundamental statements of geometry.

[Free Registration/Login Required] Students use the interactive features of Activstudio to identify and label one and two dimensional characteristics. Students explore rays, lines, end points, line segments, vertices, and angles.

This site explores linear perspective and how it was first used in the early 15th-Century. Discusses horizon line, vanishing point, and orthogonal lines. The site provides an example.

Dozens of statistical terms are defined and illustrated in this glossary.
