Pythagorean Theorem
The Pythagorean theorem is an equation used to determine the unknown side lengths of a triangle. A triangle has three sides: a, b, and c. When a side length is missing, this equation would be used by plugging in the side measurements that are given, then use algebra to determine the missing side measurement. When using the Pythagorean theorem, sides a and b are the sides with a smaller length and side c is the longest length. GeoGebra is an online application that is used as a tool to graph and construct 2D and 3D shapes. Using GeoGebra, we will learn how to construct a triangle and a square on each side of the triangle (3 squares total). Each side of the triangle will have their own length measurement and the squares will represent each side’s length-squared (what is used in the Pythagorean Theorem).
