1. Midpoint and Distance in the Coordinate Plane
Geometry
Farris 2015

2. I can develop and apply the formula for midpoint.
I can use the Distance Formula and the Pythagorean Theorem to find the distance between two points.

3. Coordinate Plane
A plane that is divided into 4 regions by a horizontal line (x – axis) and vertical line (y – axis). The location, or coordinates, of a point are given by an ordered pair. (x, y)

4. Midpoint Formula
The midpoint of two coordinates.

5. Midpoint Formula Example

6. Finding the Coordinates of an Endpoint

7. Finding endpoint example

8. Distance Formula
The distance between two points.

9. Distance Formula Example

10. Definitions
Legs – the two sides of a triangle that form the right angle.
Hypotenuse – the side across from the right angle that stretches from one leg to the other.

11. Pythagorean Theorem
In a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.
