ResourceMAP - Similar Triangles and Other Polygons - Student Edition

ResourceMAP modules are relatively short and designed for flexible implementation; that is, they can be used in regular classes as well as in special test-preparation settings. Each module contains a set of contextual problems in several formats: multi-part open response, short response, and multiple-choice. Accompanying the problem set are tip sheets that serve several purposes including lists of formulas, calculator instruction, and brief reviews of the module's underlying mathematics. Also provided are teacher notes (the module purpose, the mathematical focus, and implementation commentary), answers to all problems, and (in a few cases) handout masters.

Similar Triangles and Other Polygons

Engineers, artists, scientists, surveyors, astronomers, and pilots often need to know a length (or distance) that cannot be measured directly. For example, a surveyor might need to know the distance across a lake. People who need accurate measurements can use expensive instruments. But, as you will see in this module, it is possible to find sizes indirectly with very simple materials.
