Question

When constructing a perpendicular bisector of line segment AB using a compass, what must be true about the compass radius?

Options

• Equal to the length of AB.

• Less than half the length of AB.

• More than half the length AB.

• Any random length.

Answer 1

More than half the length AB.

Explanation:

The compass radius must be set to more than half the segment's length to ensure the arcs intersect both above and below the line, forming the necessary intersection points.
