Using a Coordinate Plane and the Pythagorean Theorem

When a triangle is placed on the coordinate plane, the lengths of each side can be measured by counting the squares/ units between each point.

When do I use the Pythagorean Theorem?

When there is a right triangle and the length of two sides are known and you are looking for the third side.

What is the Pythagorean Theorem?

C^2= A^2+ B^2

The Pythagorean Theorem is an equation that shows the relationship between the three sides of a right triangle.

Picture of the Theorem

How to find the Distance between two points on a coordinate plane.

When a triangle is placed on a coordinate plane the length of each side must be found. To find length of the two legs you must count the units between each point, and once the total number of units have been found you then you the Pythagorean Theorem to find the hypotenuse.

Variations of the Formula

C^2- A^2= B^2

C^2- B^2= A^2
