Although part of the Study Guide for the CAHSEE, this section of the document focuses on measurement and geometry. In the study guide, students are shown why this topic is important, how they will be assessed, and then given a long...

This activity is designed for students to make conjectures about triangles. Students will create three lists to represent the measures of the angles of the triangle. The entire class list will then be sent to each student for analysis,...

[Free Registration/Login may be required to access all resource tools.] Learn how to use a protractor to draw angles.

Rather than dividing a circle into some number of segments (like 360 degrees), mathematicians often prefer to measure angles using the circumference of a unit circle - a circle with radius 1. This way of measuring angles is called...

In this activity, students will practice some of the basic functions of the Cabri Geometry software, including use of the Pointer, Point, Line, Measure, and Construct toolbars.

If you want to plant a class garden, this is a great resource for combining geometry, Native American studies, and rocks.

The applets in this Interactive Geometry Dictionary (IGD) will show you how to find the area of some common shapes.

In this activity, students use the Cabri software to mark points, draw lines, construct parallel and perpendicular lines, angles, bisectors, and triangles. They learn how to use the tool to measure angles.

Students use the Cabri Jr. application to draw triangles and construct perpendicular bisectors on the sides of a triangles. They study the properties of a triangle and understand how the measures of angles of a triangle is always 180...
