Rays Teacher Resources

Rays are very useful as two rays can create an angle, multiple angles can create a polygon, and by adding another dimension you get three-dimensional solids. This tutorial introduces you to rays and shows you how to name them. [4:51]

In this lesson, students will identify and draw lines, segments, rays, angles, and points.

This illustrated physics tutorial serves as a step-by-step guide to drawing ray diagrams. It includes an opportunity for students to practice and check their answers.

In this lesson, you will learn about the various types of lines, line segments, rays, the line segment symbol, and line segment examples. Check out the interactive examples and try your hand at solving a few interesting practice...

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

Students explore this simple physics principle: In order to view an object, you must sight along a line at that object; and when you do light will come from that object to your eye along the line of sight.

Explore lines and angles, and the relationship between the two.

Brush up on your math skills pertaining to lines, line segments, and rays then try some practice problems to test your understanding.

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

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

[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...

Explains what lines, line segments, rays, and angles are, and how to measure an angle opening. [6:28]

Compares qualities of line segments, lines, and rays. Practice problems available. [3:38]

In this video the students explore the difference between lines, line segments, and rays.

This fourth-grade geometry lesson teaches the definitions for a line, ray, angle, acute angle, right angle, and obtuse angle. We also study how the size of the angle is ONLY determined by how much it has "opened" as compared to the whole...

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

[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...

Find definitions and images of line, line segment, and ray.

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...

[Free Registration/Login may be required to access all resource tools.] This concept introduces students to the basic principles and definitions of geometry, including points, lines and planes. tudents examine guided notes, review guided...

This illustrated physics tutorial uses animations to attempt to explain to students why images appear.

Through illustrated diagrams and animations, students explore the broken pencil phenomenon and light refraction.

Students take an in-depth look at the physics behind image formation.
