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 SideHypotenuse
cosθ=Adjacent SideHypotenuse
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-
sinAa=sinBb=sinCc
Where
A ,B andC are angles of the triangle.
a ,b andc are sides of the triangle opposite to anglesA ,B andC respectively.
