This is the first of two volumes designed to cover an entire year of high school geometry. The first volume topics include: symmetry, transformations, constructions, coordinate geometry, logic, congruent triangles, points of concurrency, properties of special triangles, proofs (two column, algebraic, flow, and indirect), equidistance, parallel lines, and quadrilateral properties. The second volume includes: similarity, dilations, right triangles, Pythagorean Theorem, 3d solids, right triangle trigonometry, polygons, tessellations, circles, angle/arc relationships, power theorems, area, volume, surface area, and modeling. These are all topics in the Common Core Curriculum for geometry.
