Question

the diagram below shows a partly completed construction of the perpendicular bisector of ab. complete the construction.

Explanation:

Step1: Draw a circle with center B and radius AB

Using the circle - drawing tool, set the center at point B and the radius equal to the length of segment AB.

Step2: Mark the intersection points of the two circles

Let the circle centered at A and the circle centered at B intersect at two points, say C and D.

Step3: Draw the line CD

Using the line - drawing tool, draw a straight line passing through points C and D.

Answer:

The line CD is the perpendicular bisector of segment AB.
