  1. Suppose you have to find the distance from point A to point B … and there is a slimy alligator in that pond. … and there is a slimy pond in your way A Excuse me? B

  2. Without getting your feet wet -- or nibbled on -- you can measure the distance with two little things. A measuring stick. And this Greek guy’s theory.

  3. Then measure east to point B. Start by measuring south from point A. A Three units Seven units B

  4. This is where the Greek dude comes in. His name is Pythagoras, and his theorem states that in a right triangle, the sum of the squares of the shorter legs is equal to the square of the hypotenuse.

  5. Say what? Square the length of each leg. Then add 9 + 49 and get 58. -- the hypotenuse. The square root of 58 is the length of the longest side 32 = 9 and 72 = 49 A Did you say hippo? It’s easy. B

  6. The Pythagorean Theorem is represented by a2 + b2 = c2 with the shorter legs of the right triangle being ‘a’ and ‘b’ and the hypotenuse being ‘c’. c b a

  7. So how far is it from point A to point B? A Get a calcu-gator B

  8. Press 2ND Then 7.07 units With the above it. Then 58.
