Midpoint of a Line
 |
CoordinatesI will be using Cartesian Coordinates, where you mark a point on a graph by how far along and how far up it is. |
| Example: The point (12,5) is 12 units along, and 5 units up. |
Midpoint of a Line
The midpoint is halfway between two points. So all you have to do is ... ... calculate the average x and average y of the two end points:
|
 |
And this is what you get:
| M = ( | xA+xB | , | yA+yB | ) |
| 2 | 2 |
Example: What is the midpoint here?
 |
M = ( 5/2, 4/2 ) M = ( 2.5, 2 ) |
