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

Determine which angle has a greater measure by looking at the size of the opening between the angle's rays. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Complementary and Supplementary angles are explored in this tutorial video. [9:17] A PowerPoint presentation provides definitions of angle terms and a video offers examples for finding the missing angle in a supplementary or...

Through an illustrated tutorial and some interactive practice problems, students learn about the law of reflection of light.

In this interactive physics tutorial, students will learn about a mathematical equation relating these two angles and the indices of refraction of the two materials on each side of the boundary.

In this illustrated physics tutorial, students investigate the connection between light reflection and light refraction.

Through illustrated examples and interactive practice problems, students explore the details of Snell's Law.

A list of geometry definitions and a matching activity.

Discover how light reacts when it strikes mirrors which are placed at right angles to each other.

Find a quick, concise explanation of angles and types of angles. Several examples are given to help you understand how angles are formed and the different types of angles.

Defines the refraction of light and provides an applet for investigating it.

In this Cyberchase video segment, Harry tries to snowboard and learns how to measure and identify many common angles.

[Free Registration/Login may be required to access all resource tools.] In this module, discover and solve problems involving the index of refraction, and investigate problems involving Snell's Law.

The lesson discusses commonly used geometric terms. Definitions and examples of a line segment, ray, and angle are included.

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

An interactive Java applet which allows the user to investigate the path of light through a lens shape object. The shape of the object, the index of refraction of the material, and the location of the incident rays can be altered.

[Free Registration/Login Required] Students explore identification of angles by vertex and ray by navigating through the interactive learning module and then answering questions that go along with the module. Students can also learn more...

A discussion of Christian Huygens' contribution to wave optics, and particularly to our understanding of the reflection and refraction of light. Excellent diagrams and a geometric proof on why the law of reflection is mathematically...

This site from Georgia State University is an indexing page for several other pages on the topic of reflection. Topics are treated in an understandable manner and utilize meaningful graphics.

This page is a continuation of a tutorial about light reflection and refraction. It contains a diagram and suggestions on how to derive Snell's Law, which governs the refraction of light in a medium. For background to this derivation,...

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

[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...

Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual...

This physics department site explains how prisms work and their purpose in the dispersion of light. Explains the angle of deviation and includes an interactive form in which visitors calculate the angle of deviation and receive immediate...
