draw a line segment SR of length 10 cm.Divide it into 4 equal parts using compass.

STEPS OF CONSTRUCTION

1. First draw the bisector of SR .Take a compass . With S as centre and radius more than half of SR draw two arcs above and below SR .

2. Now with R as centre and same radius cut the two arcs above and below SR at A and B.Join A and B and AB is the bisector of SR and let it join SR at Z .

3. Now draw the bisectors of SZ and ZR in the same way as we have drawn the bisector of SR .So the line segment SR will be divided into four parts.
