The edge length of the right triangle with two sides and other angles calculation tool

all you have to do is enter and calculate known measurements.

If the inner angles of the triangle and an edge are known, you can calculate the other edge

The application also works without internet


Calculator solve triangle specified by all three sides (SSS congruence law). Uses Heron's formula and trigonometric functions to calculate area and other properties of given triangle.

Enter any valid input (3 side lengths, 2 sides and an angle or 2 angle and a 1 side) and our calculator will do the rest.

Easy to use calculator to solve right triangle problems. Here you can enter two known sides or angles and calculate unknown side ,angle or area. Step-by-step explanations are provided for each calculation.


Formulas used for calculations on this page:

Pythagoras' Theorem
a2 + b2 = c2

Trigonometric functions:
sin(A) = a/c, cos(A) = b/c, tan(A) = a/b
sin(B) = b/c, cos(B) = a/c, tan(B) = b/a

Area = a*b/2, where a is height and b is base of the right triangle
