Geometry Problem Solver Scan the geometry problem, see every step
Photograph a triangle, a circle or an angle problem, crop it, and get the worked solution: what the figure is, then every step, then the answer with its units.
Triangles, circles, angles and solids. Printed or hand-drawn.
Worked solution
Right triangle, legs 6 and 8
- 1. Name the figure
A right triangle, with the right angle between the two known legs.
- 2. Pythagorean theorem
c² = a² + b² applies because the angle is 90°
- 3. Substitute
c² = 6² + 8² = 36 + 64 = 100
- 4. Result
c = 10, and the area is ½ · 6 · 8 = 24

What it covers
Triangles
Missing sides and angles, congruence and similarity, Pythagoras, law of sines and cosines.
Circles
Area, circumference, arcs, sectors, chords, tangents and inscribed angles.
Angles
Complementary, supplementary, vertical, and the ones formed by parallel lines and a transversal.
Solids
Surface area and volume of prisms, cylinders, cones, pyramids and spheres.
Six tools, one app
Problem scanner
Photograph the page, then crop to the exact problem so nothing else on the sheet confuses it. It reads the figure and its labels, which is the part a plain calculator cannot do.
Problem analysis
Before solving, it states what the figure is and what is being asked. Half the geometry mistakes happen right there.
Step-by-step solution
Every step titled and explained, ending in a clear final answer with units. That is the difference between copying and learning.
Scientific calculator
Basic and scientific modes, degrees or radians, memory keys and a running history. For when you already know the method and just need the arithmetic.
Quizzes
Forty multiple-choice questions across geometry, trigonometry, algebra and calculus, so you find the gap before the test does.
Flashcards
Forty cards on the formulas that never stick: area of a circle, the Pythagorean theorem, the sine and cosine ratios.
Questions
Does it work from a photo of the figure?
Yes, and that is the point of using it instead of a calculator. Get the whole figure in frame with its labels and the given measurements, shoot straight on rather than at an angle, and avoid a shadow across the drawing. A printed textbook figure reads more reliably than a hand-drawn one.
Does it show the steps or just the answer?
The steps, with the theorem named at each one. A bare answer is worth almost nothing when the exam asks you to show your work, and it teaches you nothing about the next problem.
Can it do proofs?
It handles the reasoning behind standard results and will lay out why each step follows. A formal two-column proof in the exact format your teacher wants is still something you should write yourself, using the steps as the skeleton.
Does it cover trigonometry?
Yes. The quizzes and flashcards cover the sine, cosine and tangent ratios and the identities alongside geometry, since most geometry problems past a certain point turn into trigonometry anyway. The calculator does both in degrees or radians.
Do I have to type the problem in?
No, and you cannot. The only way in is a photo, from the camera or your library, followed by a crop step so you can cut the page down to the single problem you care about.
Is it free?
Your first problem is free, no account needed. After that, unlimited solving and the practice tools are a subscription, weekly with a three-day trial or yearly. The calculator and your saved history stay free.
Stuck on the figure
Scan the one you cannot start, read the steps, then do the next one yourself. That is the point.
