This revised edition of Intro to Geometry links all the activities to the NCTM Standards. The activities were designed to provide students with practice in the skill areas required to understand basic geometry concepts. Activities that focus on congruence and similarity, classifying various kinds of angles and triangles, transformations, parallel and perpendicular lines, properties of geometric figures, arcs and chords, and finding surface area and volume are all part of the new edition. Examples of solution methods are presented at the top of each page. New puzzles and riddles have been added to gauge the success of the concepts learned. Contains complete answer key.
