 Finding the midpoint Midpoints: The midpoint of a line segment is the point that divides the segment into two congruent segments. If M is the midpoint of , then: AM=MB or   ;   Finding the midpoint By using x and y coordinates, it is easy to find the midpoint of a line segment. The midpoint is calculated by taking the average of the x coordinates and then taking the average of the y coordinates. If (x1,y1) and (x2,y2) are the endpoints of a segment, the midpoint is calculated by: Find the midpoint of a segment with endpoints (-15,7) and (3,9).  The midpoint is (-6,8) One endpoint of a line segment is at (-3,2) and the midpoint is at (3,-8). Where is the other endpoint?  Similarly:  The other endpoint is (9,-18)
