how to proof the midpoint formula.
The Midpoint Formula
Some coordinate geometry questions may require you to find the midpoint of line segments in the
coordinate plane. To find a point that is halfway between two given points, get
the average of the x-values and the average of the y-values.
The midpoint between the two points (x1,y1) and (x2,y2) is given by the formula
For example:
The midpoint of the points A(1,4)
and B(5,6) is
Find the midpoint given two endpoints
We can use the midpoint formula to find the midpoint when given two endpoints.
Example:
Find the midpoint of the two points A(1, -3) and B(4, 5).
