Key to Geometry Book 2: Circles
Key to Geometry introduces students to a wide range of geometric discoveries 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. When they finish, students will have been introduced to 134 geometric terms and will be ready to tackle formal proofs.
The series covers lines/segments, circles, constructions, perpendiculars, squares/rectangles, angles, and perpendiculars/parallels/chords/tangents/circles. The level includes 8 workbooks and 4 answer keys. There is not a test booklet for this topic. ~Sara
My math class has these for homework practice. We're working our way through the series before Algebra.
We love Key To Books- I can just give them to my kids, and they can work very independently.
