You're trying to measure 5 inches of bubble tape to give to your friend, but you don't have a ruler. You only have a 3 inch piece and a 4 inch piece that you had planned on eating during math class rather than listening to the teacher talk about the Pythagorean theorem, because gum is so much more interesting. But your friend is paying you for these 5 inches, so you use your 3 inch piece and your 4 inch piece to measure the piece for your friend.
A student of Euclid's once asked during a lesson on geometry asked, "But what do I gain from this?" Euclid told his slave to give the boy a coin, so that the student would see an actual profit.

If you want to make something square or perpendicular, use the 3, 4, 5 right triangle. Make a mark on the wall 4 feet up, go out 3 feet and make the diagonal 5 feet. If you assume the floor is level the wall will be vertical. Or is you are laying out some kind of rectangle on the ground do 3 one direction, 4 foot in the other and the hypotenus 5 the angel will be 90 degrees. Carpenters and masons use this quite a bit.

It involves a little more than the Pythagorean theorem (but it starts with it). Being able to figure out the length of a shadow of a building (or any object) just by knowing the angle of the sun. OR conversely, being able to figure out your latitude just by knowing the height of an object and the length of its shadow. I think that is pretty cool!
