Description
Trigonometry Pro is the essential toolkit for students, engineers, and anyone who works with triangles and angles.
Solve any triangle — instantly
Enter any two known values and let the app calculate the rest. Whether you know two sides, one side and an angle, or any other combination, Trigonometry Pro finds the complete solution.
Right Triangle Calculator
Solve using any two known values: sides (a, b, c) or angles (α, β)
Uses sine, cosine, tangent, and the Pythagorean theorem
Clearly shows which formula was applied
**General Triangle Calculator**
Supports all cases: SAS, ASA, SSA, AAS, and SSS
Uses the Law of Sines and the Law of Cosines
Automatically detects and handles the SSA ambiguous case — shows both solutions when two valid triangles exist
Theory & Learning
Animated Pythagorean proof — watch a² + b² = c² come to life step by step
Interactive unit circle — explore sine, cosine, and tangent at any angle
Right triangle reference with all key formulas
Settings
Works in degrees or radians — switch instantly in Settings
Adjustable decimal precision (2–6 places)
