Only the perpendicular bisector will determine a midpoint. The angle bisector will not, in general, find the midpoint of the side of a triangle across from the angle.

When you bisect an angle you are?

To bisect an angle means that we divide the angle into two equal (congruent) parts without actually measuring the angle.

Can a plane bisect a line?

In geometry, bisection is the division of something into two equal or congruent parts, usually by a line, which is then called a bisector. ... In three-dimensional space, bisection is usually done by a plane, also called the bisector or bisecting plane.
