Where: c is the hypotenuse of a right angle triangle and a and b are two sides containing the right angle.
This formula is applicable to any triangle. Here a, b and c are the three sides of the triangle and A, B and C are the angle opposite to these sides respectively
similarly
and
Note: This is a general law and if you make any of the angles equal to 90 degrees it gives the Pythagoras Theorem as Cos of 90 degrees = 0
This formula is applicable to any triangle. Here a, b and c are the three sides of the triangle and A, B and C are the angle opposite to these sides respectively
