To bisect an angle , we are required to bisect (i) With B as centre and any suitable radius draw an arc to cut AB at D and BC at E respectively. (ii) Take any radius greater than of ED, not necessarily the previous radius. (iii) With this radius, taking points D and E as centres, draw two arcs whic..
