  • Bisection of Lines
  • Video Illustration

The bisection of a line simply means the division of the line into two equal parts.

The diagram below is the bisection of line AB at line O. In this topic, we are going to show you the steps you need to take to bisect a line. We also created a video you can watch at the end of the topic.

bisection of lines

Steps taken to bisect a Line:

i. Draw a given line of AB = 100 mm

ii. With centre A and a convenient radius that is greater than half of AB (e.g. 70 mm) on your compass, draw arcs above and below the line.

iii. With centre B, draw arcs with the same radius as you used previously to cut the previous arcs, and call the intersection of the arcs C and D respectively.
