Bisecting an Angle Task: Bisect angle ABC. A C B X D Y Conclusion: Construction: BD is the bisector of angle ABC. Centre Y and same radius draw another arc. Join BD. Centre B and any radius draw an arc of a circle to cut BA and BC at X and Y. Label the point of intersection D. Centre X any radius draw an arc.
