Triangle Similarity. Geometry Module for Use in a Mathematics Laboratory Setting.

Brotherton, Sheila; And Others

This is one of a series of geometry modules developed for use by secondary students in a laboratory setting. The purpose of this module is to teach solution of proportions, concepts and theorems of triangle similarity, solution of the Pythagorean Theorem, solution of the isosceles right triangle, and concepts involving "rep-tile" figures as well as pentominoes. Topics reviewed briefly include ratio and proportion, size transformations and a review of terminology covered in previous sections. These purposes are accomplished by the use of detailed examples, narrative explanations, and drawings. (Author/MK)
