Definition

A midpoint is the point that is exactly halfway between the two endpoints of a line segment.


  • It divides the segment into two equal parts.

  • If the segment is on a coordinate plane, the midpoint can be found using the midpoint formula:


Open parentheses x one plus x two divided by two comma y one plus y two divided by two close parentheses.

This gives the coordinates of the point that is right in the middle of the segment.
