Outcomes, not lecture notes.
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.
Make the Basics Automatic When a student is still working hard on solving equations or slope and the coordinate plane, there's little attention left for the new idea that builds on it. We revisit those foundations until they're automatic, so students' brainpower goes where it's needed most.
Lock In This Year's Learning Geometry moves fast, and each unit leans on the last. We circle back to key concepts from earlier in the year, like angle relationships or congruent and similar triangles, so later units have something solid to build on.
Tackle What's in Front of You Whatever unit your class is in right now, from proofs and congruence to right-triangle trigonometry and circles, students get guided practice and clear strategies for the kinds of problems they're seeing in school this month.
Preview What's Next Wouldn't we all love a sneak peek at our next challenge before the clock starts ticking and the points start counting? We preview upcoming concepts, like trigonometric ratios or volume formulas, so new topics feel familiar instead of intimidating.
