Question

draw a line segment PQ= 8.4cm. Divide PQ into four equal parts using ruler & compass.

Answer 1

This is the way you would do it.
Steps of Construction
- draw PQ equals to 8.4 centimetres
- draw the perpendicular bisector of PQ
- let it meet at point M
- draw perpendicular bisectors of PM and MQ
- let them meet at point R and S respectively.
therefore, required line PQ is divided into 4 equal parts that is PR equals to RM equals to MS equals to SQ equals to 2.1 centimetre
