Pythagorean Theorem in real life

When do we use the Pythagorean Theorem besides in our everyday math class? The Pythagorean Theorem is a good measuring tool when you don't have a ruler.

Take a baseball diamond for example. If I wanted to measure the distance between home plate and second base knowing that the angle at first base is a right angle and also knowing the lines between first base to home and first base to second are 90 feet, you would use the Pythagorean Theorem to find the hypotenuse. The Hypotenuse is second base to home plate.

Have you ever gone apple picking? Do you climb up high in the tree to reach an apple? Let's say you are in that tree and you are about 3 feet off the ground. Now lets say that the tree and the ground make a right angle, and the basket holding the apples to the tree is about 6 feet away. How far away would you be to the basket? What you would do is do 3 feet squared which makes it 9 and then you would do 6 feet squared which makes that 36. 36+9=C squared. Once you add 36 and 9 you get 25. 25= C squared. Not done yet! Now you have to find the square root of booth C squared and 25. The square root of C squared is just C and the square root of 25 is 5. So C=5feet! You are 5 feet away from the basket!
