Right Triangle Solver

Shop Geometry

Choose the two values you know from the print or measurement. Only those inputs are shown, and the calculator solves the complete right triangle.

Known ValuesSelect exactly two known values from the print or measurement.

Side A

Side B

Hypotenuse

Angle θ (theta)

deg

Angle between Side A and the hypotenuse Angle β (beta)

deg

Complement of Angle θ

Calculation Rules

The solver uses the Pythagorean theorem and standard right-triangle trigonometry. Two angles alone cannot define a triangle because they do not establish scale.

Angle θ is measured between Side A and the hypotenuse. Angle β is its complement, so θ + β = 90°.
