__It's the Right Thing Lesson Plan__

In this lesson, students will learn the six types
of triangles and the characteristics each one
possesses. They will learn to read the degrees of an
angle using a protractor, be able to determine
proportions between heights and shadows, use ratio to
find an unmeasureable object through the height to its
shadow, understand the Pythagorean Theorem and how to
use the formula, and learn to evaluate and compare
congruent and similar right triangles. Using Microsoft
Excel, students will compare sizes of the two legs of
the right angle to find that the ratio between the
height and the shadow are in proportion to each other.
