Bisect
To bisect a line you split into two equal parts.
Buy secators (Bisect) and cut sticks in half.
You bisect a line as follows:
Measure the halfway point between A & B.
You now have the bisection point.
NOTE:
If you draw a line at 90° to this bisection point.
You now have a perpendicular bisection of the line A-B.
