A Right Triangle with Legs A and B has a third side C (the hypotenuse). The hypotenuse C = SQRT(a^2 + b^2)

or c^2=a^2+b^2

Calculating the Hypotenuse of a Right Triangle When Given Two Leg Lengths

Legs

Lengths

B =

Hypotenuse (C)= A^2+B^2

Area = (1/2)*A*B

Using the Hypotenuse and One Leg Length You can Calcualte the Third Leg.

Sides

One Leg =

or

Length of Leg =

Area = (1/2)*Leg*Leg
