High School Geometry Help


High School Geometry focuses on Euclidean based plane coordinate geometry. High School Geometry curriculum spans from basic topics of lines, triangles, and circles to complex topics including locus of points, and transformations. Important topics include proving triangles congruent, areas of polygons, and reflections, rotations, and dilations.
