Geometry [Honors] gives students a strong foundation in the subject as they formulate mathematical arguments and create geometric constructions. The course begins with a study of points, lines, planes, segments, and angles. Students practice an essential geometric skill: constructing and analyzing a variety of proofs. An in-depth coverage of triangles begins as students explore congruent triangles; special parts including bisectors, medians, and altitudes; and triangle theorems. Students then explore more shapes and calculate area, perimeter, and midsegments. Similarity is covered next, as students work with similarity tests for triangles, ratios, and scale drawings. Students explore geometry on the coordinate plane as they perform transformations and create tessellations. Trigonometric ratios and the laws of sines and cosines are used to solve problems. An in-depth study of circles follows, including sectors, inscribed angles, special arcs, and tangents. Students extend their knowledge to conic sections and three-dimensional figures as they work with surface area, volume, density based modeling, and design problems.
