Bisecting a line

Bisecting a line is cutting a line exactly in half. It may also be referred to as constructing a perpendicular bisector as the line you are drawing will be at a right angle to the original line.

You will need a compass, pencil and ruler. Do not rub out any of the construction lines, these will show that you used a compass and didn't measure where the line should be.

To bisect this line, set your compass to just over half the length of the line. Keep your compass this size for the rest of the question.
