This revised edition of 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 geometry concepts. Reviewing concepts presented in a beginning geometry course plus exercises involving symmetry, rotations, translations, fractals, the coordinate plane, parallel lines, two-column proofs, intersections, bisecting angles, sectors and arcs, tangents, properties of geometric figures, surface area and volume, and trigonometry are all part of this 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 concepts learned. Contains complete answer key.
