Here are the steps:
0.Construct a 60° angle.
1.Draw an arc cutting the both arms of the ∠(say ∠ABC) , at D and E.
2.With D and E as centers and any suitable radius which is (\ \textgreater \  \frac{1}{2} DE), draw arcs which cut each other at F.
3.Join B and F and extend to G.
⇒Hence ∠ABG=∠GBC=30°.
Hence 60° angle is bisected.

Aim:
Draw an angle of  60° 
Steps of construction:
Draw an arc cutting the both arms of the ∠(say ∠ABC) , at D and E.
With D and E as centers and any suitable radius more than half of DE, draw 2 arcs which cross each other at F.
Join B and F and extend to G.
⇒Hence ∠ABG=∠GBC=30°.
Hence an angle of 60° is bisected.
