An Experimental Text in Transformational Geometry, Student Text; Cambridge Conference on School Mathematics Feasibility Study No. 43a.
Cambridge Conference on School Mathematics, Newton, MA.
This is part of a student text which was written with the aim of reflecting the thinking of The Cambridge Conference on School Mathematics (CCSM) regarding the goals and objectives for mathematics. The instructional materials were developed for teaching geometry in the secondary schools. This document is chapter six and titled Motions and Transformations. Presented is the concept of rigid motion in the plane. Various kinds of rigid motions are considered, certain mathematical ideas about rigid motions are obtained, and a number of applications are described. One of the chief mathematical ideas presented is that every rigid motion can be viewed either as a translation, a rotation, a reflection, or a combination of reflection and translation. This idea and others lead to a variety of useful applications in geometry. Several of these applications involving rigid motions are used to solve geometrical problems. Both explanatory materials and student problems are included. [Not available in hard copy due to marginal legibility of original document]. (RP)
