Pythagorean Theorem Calculator

## Step 1:

Enter the values of any two angles and any one side of a triangle below for which you want to find the length of the remaining two sides.

The Pythagorean theorem calculator finds the length of the remaining two sides of a given triangle using sine law or definitions of trigonometric functions.

If a given triangle is a right angle triangle, then the length of the remaining two sides of the triangle can be calculated using the definition of sine and cosine functions given by the formula-

$sinθ= Opposite Side Hypotenuse$

$cosθ= Adjacent Side Hypotenuse$

If a given triangle is not a right angle triangle, then the length of the remaining two sides of the triangle can be calculated using the sine law given by the formula-

$sinA a = sinB b = sinC c$

Where A, B and C are angles of the triangle.

a,b and c are sides of the triangle opposite to angles A,B and C respectively.
