Geometry Solver
Describe the shape and its measurements in plain English — “volume of a cylinder radius 3 height 5” — and get the formula, the substitution and an exact answer in terms of π.
- Every answer independently verified
- Results in milliseconds
- AI explanations at your level
What the geometry solver can do
Area & perimeter
trapezoid with bases 6 and 10
Rectangles, circles, triangles, trapezoids.
Volume & surface area
sphere radius 3
Cubes, prisms, cylinders, cones, spheres.
Right triangles
legs 8 and 15
Pythagorean theorem with verification.
Any triangle
sides 7, 8, 9
Heron's formula, laws of sines and cosines.
Coordinate geometry
slope through (1, 2), (4, 8)
Slope, distance and midpoint.
Trigonometry
sin(π/6)
Exact values and trig equations.
Accuracy by design
A math engine first. AI second.
Chatbots guess. We compute, verify, and then explain — so every explanation is about a correct answer.
- 01
Understand
Your input — text, LaTeX, keyboard or photo — is normalized and classified into one of 20+ problem types.
- 02
Compute
A symbolic math engine solves it exactly: algebra, calculus, matrices, statistics.
- 03
Verify
Independent checks confirm the answer: substitution, numerical differentiation & integration, round-trips.
- 04
Explain
AI explains each verified step at your level — and can never change the answer.
Exact answers in terms of π
Geometry answers are kept exact where possible (25π) with a decimal approximation, and the units you type are carried into the answer (cm², ft³).
