Bisect
"Bisect" means to divide into two equal parts.
We can bisect lines, angles and more.
The dividing line is called the "bisector".
Bisecting a Line Segment
Here the blue line segment is bisected by the red line:
You can try it yourself (try moving the points):

When the bisector is perpendicular (at right angles) to the line being bisected it is called a "perpendicular bisector".

Bisecting an Angle
Here the blue angle is bisected by the red line:

Bisect a Shape
We can also bisect some shapes. Here a kite is bisected by a dashed line:
