Pythagorean Theorem Tutorial Back to Activities page

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 A = B = or Hypotenuse (C)= SQRT( A^2+B^2) Area = (1/2)*A*B     Using the Hypotenuse and One Leg Length You can Calcualte the Third Leg. Sides Lengths Hypotenuse = One Leg = or Length of Leg = Area = (1/2)*Leg*Leg Illinois Learning Standards STATE GOAL 9: Use geometric methods to analyze, categorize and draw conclusions about points, lines, planes and space. 9.A.5 Use geometric figures and their properties to solve problems in the arts, the physical and life sciences and the building trades, with and without the use of technology. 9.B.4 Recognize and apply relationships within and among geometric figures.
