Congruence and Construction. 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. This module, intended to present a treatment of congruent triangles which is not totally axiomatic, contains six sections: (1) Draw vs. Construct; (2) Triangle Construction; (3) Arguing for Congruence; (4) Parallel Line Construction; (5) Altitudes, Medians, and Angle Bisectors; and (6) Triangle Inequalities. The module includes compass and straight-edge constructions as a tool in the investigation of triangles, which allows for the de-emphasis of the deductive system by making use of inductively drawing conclusions. The module includes teaching suggestions and activities for each section. (MK)
