To bisect is to cut into two equal halves. In geometry, bisecting an angle means divide the angle into two equal angles. Bisecting a line segment means dividing the line segment into two equal line segments.

Manipulative 1 - Bisecting a Line Segment Using Analytical Geometry Created with GeoGebra.

Using analytical geometry, a line segment can be bisected. If the endpoints of the line segment are (x1,y1) and (x2,y2), then the midpoint of the line segment is Open parenthesis (x1+x2)/2, (y1+y2)/2 close parenthesis (see figure 2).
