Geometry introduces high school students to concepts of formal logic. Students study the material of Euclidean plane geometry, in particular, the properties of geometric figures, including triangles, polygons, and circles. Congruence and similarity of figures is covered as well as the calculation of area and volume of two and three‐dimensional figures–both known and novel. Students perform straightedge and compass constructions and use those techniques of construction to create art and other renderings to be used in larger design projects. The Pythagorean Theorem and right‐triangle trigonometry are key concepts of the course. In the end, the course finishes with an introduction to applications of linear functions used to model “real world” phenomenon that enables discussions of domains, ranges, extrapolation, and interpolation. Algebra skills are incorporated throughout the course to maintain readiness for Algebra II. Prerequisite: Successful completion of Algebra 1
