Draw a line segment AB = 5 cm.2. With any radius greater than 2.5 cm, and compass fixed at A, draw 2 arcs, one above and one below AB.3. With the same radius, compass at B, cut the 2 arcs drawn in step 2.4. The line joining these two arcs is the perpendicular bisector of AB. i.e. CD is the perpendicular bisector of AB.
