Online geometry lessons for grades 8–12
Turn geometry frustrationinto quiet confidence.
Geometry Mastery Academy is a complete online geometry course for grades 8–12, covering every unit from points and lines to area and volume. You get worked examples, adaptive practice, and an AI coach that answers when frustration hits at 9pm. If shapes and theorems feel like a foreign language, you're not behind — you just haven't been taught the way you learn.
10 days free. A card is required to start, but you won't be charged until the trial ends.

235 lessons aligned to Common Core HS Geometry (HSG) standards — covering Foundations, Angles, Triangles, Polygons, Similarity, Circles, Transformations, Coordinate Geometry, Area & Volume, and Trigonometry.
Built for geometry only: grades 8–12 geometry and the geometry sections of the SAT and ACT. If you need algebra, calculus, or a full math curriculum, this isn't the right fit.

This is what changes.
We built every feature around one question: what does a student need to stop feeling lost — and start feeling capable?
Everything They Need — To Finally Feel Capable
Lessons That Finally Make Sense
Visual, step-by-step lessons that meet students where they are — so "I don't get it" turns into "oh, that's why."
A Coach That Never Gives Up on Them
Patient, 24/7 guidance that asks the right questions — so students find the answer themselves and actually remember it.
Wins Worth Celebrating
Streaks, badges, and levels that turn "I have to study" into "I want to keep going" — one small victory at a time.
Test Day Without the Panic
Real SAT/ACT-style practice that builds familiarity and calm — so the big test feels like something they've already beaten.
A Real Person When It Matters
Live tutoring with experts who care — because sometimes the breakthrough needs a human voice.
Geometry They Can See in Their World
From sports fields to architecture — lessons that connect shapes to real life, so it stops feeling pointless.
We watched too many students give up on themselves.
For the student
Who whispers "I'm just not a math person" after one bad test — and starts to believe it.
For the parent
Who's run out of ways to explain it — and hates watching frustration turn into tears at the kitchen table.
For the teacher
Who knows every kid can get it — if only they had the time and tools to reach each one.
That moment — the one where confusion turns into "oh, that's why" — is the moment a student starts to believe in themselves again.
That's the whole mission. Not better grades for their own sake, but the look on a student's face when geometry stops being a wall. It's a door, and they just walked through it.
But isn't Khan Academy free?
It is — and for some families it's a fine start. Here's the honest difference, so you can decide what your student actually needs.
Free sites explain. We teach, coach, and report back.
Geometry is all we do
235 lessons built for high-school geometry — from foundations to trig — not one unit buried inside an all-subject library.
A coach at 9pm
When homework frustration hits, the AI Coach guides your student step-by-step and never makes them feel small. A video can't ask how it's going.
You actually know how it's going
A weekly report with mastery data per topic — what improved, what's still shaky. Free sites leave parents guessing.
A real teacher behind every lesson
Built by a classroom geometry teacher with 21+ years of experience, with live one-on-one tutoring when a breakthrough needs a human.

Guidelines & Terms
The short version of how we keep this a safe place to learn — and what you're agreeing to.
How we treat each other
Be kind, always
No bullying, harassment, or hurtful language — in messages, reports, or anything you share with tutors.
Use it to learn, not to cheat
The AI Coach guides you to answers; it won't just hand them over. Use that help to understand — never to submit work that isn't yours.
Keep your account to yourself
Never share your login with anyone. Account sharing can get access suspended.
Speak up if something's off
Report any message that feels unsafe, unkind, or wrong — right from the chat. A trusted adult can help too.
The terms, in plain English
Who can use it
Students 13 and up may register with a parent or guardian's permission. Younger students join through a teacher's classroom or a parent-managed Family plan.
Subscriptions
Plans renew automatically (monthly or annually) until you cancel — cancel anytime in your account settings and you keep access through the paid period.
Refunds
Annual plans include a 7-day money-back guarantee with light use, plus protections for unused auto-renewals. Monthly charges are non-refundable.
Your privacy & safety
We never sell your data. AI Coach data is only used with consent, and parents can review or delete it at any time.
