Midpoint
In geometry, the midpoint is a point that is in the middle of a line segment. It is the point that divides a line segment into two congruent line segments.
Point C is the midpoint of line segment ABe, so ≅
We can find the coordinates of the midpoint of a line segment by taking the average of the x- and y-coordinates of the line segment's endpoints. If (x1, y1) and (x2, y2) are the endpoints of a line segment, the coordinates of the midpoint, C, can be determined as follows:
Example:
Given that points A and B are located at (-5, 2) and (3, 4) respectively, we can find the position of midpoint C:
Bisectors
The bisector of a line segment is a line, ray, or line segment that intersects the line segment at its midpoint.
Line segment ST above bisects line segment PR at its midpoint Q.
