Ladder
Pythagorean Theorem- Use the Pythagorean Theorem to determine the length of a ladder needed to scale a wall given the height of the wall and the horizontal distance from the base of the ladder to the wall. This allows you to acquire the correctly sized ladder. Not one too short so that you can't reach the top of the wall, and not one too long so that it goes way over the top of the wall.

Pool Bottom
Pythagorean Theorem- When constructing a pool with a shallow and deep end, you will need to know how much long the pool bottom will be in order to determine the amount of concrete you will need. You know the length of the pool, the depth and the shallow end, and the depth at the deep end. To find the length of the bottom of the pool, simply plug the length of the pool in as one leg, and the vertical distance between the shallow and deep end as the other leg and use the Pythagorean theorem to determine the length of the bottom which would be the hypotenuse of the right triangle these lengths form.

Kite
Pythagorean Theorem- A dad is out flying a kite with his daughter, and she wants to know how high their kite is. The dad, knowing the length of the kite string and the horizontal distance of the kite from him can easily calculate the height of the kite by using the Pythagorean Theorem. The horizontal distance would be the length of one leg and the kite string would be the hypotenuse. Now simply subtract the square of the horizontal distance from the square of the length of the kite string and square root your result, giving you the distance from the kite to your hand. Then add the distance from your hand to the ground, giving you the vertical distance from the kite to the ground.

Golf
Pythagorean Theorem- Bob is playing top golf, and in order to hit the golf ball into the hole he needs to know the distance from the platform to the hole. Bob already knows the horizontal distance & the vertical distance from the platform to the whole. Now he can use the Pythagorean Theorem and plug in these values to get the distance from the platform to the hole. Bob can now excel at top golf.
