AI Geometry Solver
Stuck on a proof, an angle chase or a volume question? Paste the problem or upload a photo of the diagram and get a step-by-step geometry solution that names the theorem behind every line.

What it solves
Two-column proofs
Every statement paired with the theorem, postulate or definition that justifies it — congruence, parallel lines, CPCTC and more.
Solve from a diagram
Photograph the figure from your textbook or worksheet. Labelled angles, tick marks and side lengths are read straight off the image.
Circle theorems
Inscribed angles, tangents, chords, arcs and sector area, with the rule named at each step instead of a bare final number.
Triangles & trigonometry
Pythagorean theorem, similarity ratios, special right triangles, law of sines and cosines, with the algebra written out in full.
Area, surface area & volume
Composite 2D shapes and 3D solids — the formula, the substitution, and the units carried through the whole calculation.
Coordinate geometry
Distance, midpoint, slope, equations of lines and circles, and transformations on the plane, shown one move at a time.
How it works
- 1
Describe the figure or upload it
Type the problem, or attach a photo of the diagram straight from your phone camera.
- 2
Get the worked reasoning
The solution arrives step by step with the geometry rule behind each line, formatted with proper math notation.
- 3
Ask follow-up questions
Stay in the same conversation and ask why a step works until the method actually makes sense.
Geometry solver FAQ
Can the AI geometry solver do two-column proofs?
Yes. Paste the given information and what you need to prove, and the solver lays out each statement with the theorem or postulate that justifies it, so you can follow the reasoning line by line.
Can I upload a photo of a geometry diagram?
Yes. You can attach a photo or screenshot of the figure. The solver reads labelled angles, side lengths and markings from the image and works from the diagram itself.
Which geometry topics are covered?
Angle relationships, triangle congruence and similarity, the Pythagorean theorem, circle theorems, polygons, coordinate geometry, transformations, area, surface area and volume.
Is the geometry solver free?
You get 2 free answers when you create an account. Pro is $9.99 per month for unlimited step-by-step solutions.
Ready for your next proof?
Open the solver, paste the problem or the diagram, and keep asking follow-ups until the method sticks.
