# What is the difference between a bisector and a perpendicular bisector?

For example, in the picture, if $\overline{D E} \cong \overline{E B}$, then $\overline{A C}$ is the bisector of $\overline{D C}$ since it split it into two equal sections.
Here, $\overline{D E}$ is the perpendicular bisector of $\overline{A C}$ since $\overline{A C}$ is split into two congruent segments—$\overline{A E}$ and $\overline{E C}$.
