Key to Geometry: Angles (Key to Geometry, 6)
Key to Geometry Angles - Key to Geometry, 6 Author:Newton Hawley, Patrick Suppes, George Gearhart, Peter Rasmussen Key to Geometry offers a non-intimidating way to prepare students for formal geometry as they do step-by-step constructions. Using only a pencil, compass, and straightedge, students begin by drawing lines, bisecting angles, and reproducing segments. Later they do sophisticated constructions involving over a dozen steps and are prompted to form t... more »heir own generalizations. When they finish, students have been introduced to 134 geometric terms and are ready to tackle formal proofs. Book 6 covers the topic of Angles.« less
