Subject Area: Geometry

Grade Level: 10 - 11

National Mathematics Standard:

Deduce properties of, and relationships between, figures from given assumptions.

National Technology Standards:

• Research Tools - Use content-specific tools, software and simulations (e.g., environmental probes, graphing calculators, exploratory environments, Web tools) to support learning and research.
• Problem-Solving and Decision-Making Tools - Routinely and efficiently use on-line information resources to meet needs for collaboration, research, publications, communications, and productivity.

Objective:

You will be able to prove angles congruent by use of the alternate interior angle theorem.

Beginner's Guide to Aerodynamics is a "textbook" of information prepared at NASA Glenn Research Center to help you better understand how airplanes work. Click Beginner's Guide Index to access the list of slides. Open the slide called Glide Angle (with text) to learn about how a glide angle measures the flying efficiency of the glider. Then complete the problem set found at Geometry Problems Set II to demonstrate your ability to prove angles congruent.

Assessment:

You will be evaluated on your proof to the problem.

 Evaluation:

You will be able to prove that the angles are congruent by the alternate interior angle theorem.
