The Pythagorean Theorem
Today you will get to explore the Pythagorean theorem. Your journey will give you the opportunity to discover what this really means and what it looks like. Today we want to find out as much as possible about this theorem, so that we can use it later to find out answers to some real life problems. Some examples of real life problems are; finding the distance across a lake, the height of a tree, the length of a handrail for a set of stairs, or the distance a plane in the air is from the ground.
