Question

AB is a line of length 6 cm. Construct a line perpendicular to AB. [4 MARKS]

Answer 1

Each step: 1 Mark

Step 1: Draw a line of length 6 cm. Mark a point P on it.

Step 2: With P as the centre and a convenient radius, construct an arc intersecting the line l at two points A and B.

Step 3: With A and B as centres and a radius 3 cm, construct two arcs, which cut each other at Q.

Step 4: Join PQ. Then PQ is perpendicular to l
