The Pythagorean Theorem

Overview: You will learn more vocabulary and how to work with the Pythagorean theorem. This will help you in life so you can figure out the missing angle to a triangle.
Definition: the theorem that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.

Example: There is a park that has an area of 40 feet long and 20 feet wide. There is a walking track that's from the top left side to the bottom right side. How long is the track?
Step 1: Draw out the problem. Make sure you label everything so you will not get confused on your next step.
Step 2: There is a triangle in the picture. Once you find it highlight it like the picture shown below. 
Step 3: Label all the sides of the triangle. The legs are a and b and the hypotenuse is c.

A squared is one of the legs, it doesn't matter which one. B squared is the other leg. C squared is hypotenuse.
Step 4: Put the problem into the equation.
Step 5: Solve the equation.

Step 6: Write the answer to the equation- The sidewalk is 50 ft long.
