Basic
Airplane Aerodynamics
Geometry
Activity I
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 vertical angles definition,
subtraction postulate, and transitivity postulate.
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
Vector Balance of Forces for
a Glider (with text) to learn about the balance of forces
on a descending glider. Then complete the problem set found at Geometry
Activity I to demonstrate your ability to prove angles congruent.
Assessment:
You will
be evaluated on your proofs to the problem set.
Evaluation:
You will
be able to prove angles congruent by the definition of vertical angles
(Problem 1), by the subtraction postulate (Problem 2), and by the transitivity
postulate (Problem 3).
