Geometry Solver: AI Help

Geometry solver with proofs. Photograph a geometry problem to get the answer, the theorem behind it and a proof you can hand in.

GEOMETRY PROOFS
This geometry solver writes two-column proofs with statements and reasons, or paragraph proofs. Every reason cites a named theorem or definition, since a step without justification earns no marks regardless of being true.

CIRCLE THEOREMS
All the standard results: angle at the centre, angles in the same segment, the angle in a semicircle, cyclic quadrilaterals, tangent-radius perpendicularity and the alternate segment theorem.

WHAT THIS GEOMETRY SOLVER COVERS
• Triangle congruence and similarity
• Pythagoras and its converse
• Parallel lines and angle relationships
• Polygon interior and exterior angles
• Area, perimeter and composite figures
• Surface area and volume of solids
• Sine and cosine rules
• Coordinate geometry and transformations

Tick marks for equal sides, arcs for equal angles, the square for right angles — notation that often carries information appearing nowhere in the written question.
