This one activity requires young geometers to pull together information they are currently learning with things they have learned previously. Here they rely on understanding something about parallel lines, alternative interior angles,...

It may be gruesome but somebody's got to do it! Young forensic scientists get a feel for what the job entails as they study blood spatter in seven experimental activites. They examine how spatter can be changed by release height,...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

Study Vertical, Adjacent, and Supplementary Angles with Cabri Jr. Page numbers come from Prentice Hall Geometry textbook.

Students will investigate the properties of angles formed by intersecting lines. They examine the definition of adjacent angles, supplementary angles, and vertical angles and learn about two important geometric theorems dealing with...

In this activity, students will measure angles and investigate the relationships between interior and exterior angles of a triangle. They understand the definition of interior angles, exterior angles, adjacent angles, supplementary...

In this activity, students visualize and explore the angles that are formed when two lines intersect. By measuring angles formed by intersecting lines, they enhance their understanding of vertical angles, supplementary angles, and a...

This activity uses Cabri Jr. to discover that opposite angles in a cyclic quadrilateral are supplementary

This geometry resource investigates types of angles. Definitions, detailed examples, and practice problems are included.

Read a description of intersecting lines and all about the different kinds of angles they form. Includes examples.

Practice using your graphing calculator for drawing and labeling points, lines, planes, and angles. If you get stumped or if you would like to check your work, then select the View Solution button, which is located directly under each...

Try these three problems about finding the measures of different angles that arise from diagrams involving parallel lines and transversals. Detailed solutions are written out for these three problems of moderate difficulty.

Definitions and properties of angles in geometry are explored. Topics discussed are right, acute, and complementary angles. Practice exercises with solutions are included.

A guide to solving problems involving numbers, rectangles, and angles. You'll learn how to employ Polya's four steps: understand the problem, devise a plan, carry out the plan, and look back.

In Spanish. Observe the relationships between the trigonometric functions then test your knowledge with the activities at the end.

This unit could be used as supplementary material for Geometry. It has good examples with illustrations and some interactive activities.
