Pythagorean Theorem Wrap-up

In my opinion the Pythagorean Theorem method is very useful because the formula (a^2+b^2=c^2) helps you find the missing side of the right triangle. REMEMBER this formula can only be used for right triangles. The hypotenuse is the longest side of the right triangle opposite of the right angle. The legs however are the smallest sides of the right triangle.
For example, the distance from the corner of the ice ring to the other side is 30 yards. The distance from the corner of the ice ring to the left side of the ring is 40 yards. What is the distance from the corner of the ring to the middle of the ring?

Well first you have to apply the formula a^2+b^2=c^2. Then plug in your numbers for the variables. 30^2+40^2=c^2. Then solve for a and b. 600+1600=c^2. Then you add that and you get 2200. Finally take the square root from both sides. You'll get about 46.9.
