Apply SSS, SAS, ASA, AAS, and HL postulates to prove triangle congruence and use CPCTC to draw further conclusions
Establish triangle similarity using AA, SAS, and SSS theorems and solve for unknown side lengths with proportions
Use the distance formula, midpoint formula, and slope relationships to solve coordinate geometry problems
Solve for missing sides and angles in right triangles using the Pythagorean theorem, special right triangle ratios (45-45-90 and 30-60-90), and SOH-CAH-TOA
Identify and apply angle relationships — including alternate interior, alternate exterior, corresponding, vertical, supplementary, and complementary angles — to solve algebraic problems
Execute and analyze transformations (translations, rotations, reflections, and dilations) on the coordinate plane
Calculate area, surface area, and volume for 2D and 3D figures including prisms, pyramids, cylinders, cones, and spheres
Apply circle theorems involving inscribed angles, central angles, chords, tangents, and secants, and work with the standard equation of a circle (x − h)² + (y − k)² = r²

High School Geometry Fundamentals is a year-round supplemental course designed for driven students who are currently taking Geometry in school and want more than a passing grade — they want to truly own the material. While school pacing moves fast and tests come and go, this course gives students the dedicated practice space to build deep, durable mastery of the concepts that Precalculus, Trigonometry, standardized tests, and college math will all depend on. Each session sharpens skills across the full geometry landscape: triangle congruence and similarity, coordinate geometry, right triangle trigonometry, circle theorems, transformations, and area, surface area, and volume. Students who invest here don't just survive their Geometry class — they walk into every future math course with a genuine, lasting advantage.
