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 lesson, young scholars will identify and draw lines, segments, rays, angles, and points.

Provides details about the properties of straight lines, types of straight lines, line segments, rays, curved lines, and types of angles.

Recognize rays, lines, and line segments in geometric figures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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

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

Students explore four types of angles in this interactive web lesson.

[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 students will explore angles, rays, line segments, perpendicular lines, parallel lines, and two-dimensional figures through the use of the book Shape Up! Fun With Triangles and Other Polygons by David A. Adler. They will also...

This interactive resource provides an example picture of the geometric figure chosen by students to review.
