Bisect

To bisect a line you split into two equal parts.

Bisection is splitting a line into 2 equal parts

Buy secators (Bisect) and cut sticks in half.

You bisect a line as follows:

Bisect this line between A and B

Measure the halfway point between A & B.

Measure the mid point

You now have the bisection point.

Draw a blob on the bisection to remind you

NOTE:

If you draw a line at 90° to this bisection point.

Draw a perpendicular line through A and B and through the bisection

You now have a perpendicular bisection of the line A-B.
