5. Path Next Previous The Pythagorean Theorem The Pythagorean Theorem is one of the most well-known mathematical theorems. It has been proven by many different methods and entire books have been devoted to investigating its properties. Pythagoras is thought to be the first person to actually prove the theorem, although the Babylonians are believed to have discovered it about 1000 years before Pythagoras.

11. Path Next Previous Let’s see how this would work We know the amount of incline that is allowed, the rise. We know the amount of distance required to cover, the run. We can calculate the ramp distance needed to accommodate these dimensions. a 2 + b 2 = c 2

12. Path Next Previous Another Use – Baseball How difficult is it to hit a homerun in say – Fenway park, where they have the Green Monster in left field? Let’s check it out.

13. Path Next Previous Baseball To find out how far a baseball must be hit to clear the Green Monster in left field at Fenway Park in Boston, you can use the Pythagorean Theorem. Find out how tall the wall is and how far it is away from home plate. These measurements create a right triangle and you can find out how far a ball needs to be hit.

16. Path Next Previous Field Goals Now that you know how far the goalpost is off the ground, and you can find out how far the kicker is from the goal line, you can determine how far the football must be kicked to just clear the goalpost cross bar.
