Enter any two values of a right triangle (sides or angles) and solve for all remaining properties. Angle C is always 90°.
Select what each value represents, then enter the number.
| Function | Definition |
|---|---|
| sin(A) | a / c (opposite / hypotenuse) |
| cos(A) | b / c (adjacent / hypotenuse) |
| tan(A) | a / b (opposite / adjacent) |
| Pythagorean | a² + b² = c² |
| A + B | = 90° (always) |
