What does it mean to bisect?
Let us say we have an angle, like so:
Let us say we wanted to draw a line that divides each of the angles into two equal parts; i.e. bisect it.
Now, . Thus, is an internal angle bisector of .

Angle bisectors are lines that divide an angle in two equal halves.

In the image above, a large slice of pie is cut into two equal slices. Can you identify the angle bisector in the image above?

Now, a more "mathematical" version.

Try the following problem!

Which line segment(s) are angle bisector(s)?
