Pythagorean Theorem

Pythagorean Theorem

1. Who made the Pythagorean Theorem

   • Pythagoras

2. Important Terms

   • Area
     • Size of a surface. Determined by multiplying legth and width.
   • Square Root
     • Inverse operation of exponents. It helps to look for the base of an exponent.
   • Perfect Square
     • Square that has equal sides and 90-degree angles.
   • Right Triangle
     • A triangle that has one 90 degree side.
   • Leg
     • Striaght lines inside a right traingle.
   • Hypotenuse
     • Side of a right triangle that is opposite to the 90-degree angle.

3. What is the Pythagorean Theorem?

   • It's where you make squares out of the legs of the right triangle. You use the length of leg to determine the size of that square. You do that for the second leg as well. You then determine the area for each square. You can do this by either counting the squares inside or by multiplying the length by itself. You add the areas to get the area of the hypotenuse side. This can help determine the length of the hypotenuse and can also determine if the triangle is a right triangle.

4. Example

   • As you can see we are trying to find out if this shape is a right triangle. Since we already have the area of both of the leg sides. We simply add them to get the area of the hypotenuse. If the area isn't what your answer was then the traingle is not a right triangle.
