Trigonometry calculator Right triangle calculator. Enter one side and second value and press the Calculate button:

To calculate the tangent ratio, you must know the length of the legs of the right triangle you're working on. If you don't know the length of a leg, use the Pythagorean theorem to obtain it from the hypotenuse.. Once you know the length of the legs, calculate both the ratios: your results are the tangents of the two acute angles of the right triangle. . If you want to calculate the angles, …

Tangent Calculator. The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side: so called because it can be represented as a line segment tangent to the circle, that is the line that touches the circle, from Latin linea tangens or touching line (cf. tangere, to touch).
