Definition
The midpoint formula is a mathematical rule used in Geometry to find the exact center point between two points on a coordinate plane.
The midpoint formula is:
What it means:
(x1, y1) and (x2, y2) are the coordinates of the two endpoints of a segment.
The formula gives the coordinates of the point exactly halfway between them — the midpoint.
It’s like averaging the x-values and the y-values to find the center between the two points.
