How to draw an angle bisector

Step 1: Locate the original diagram of the angle.
Step 2 :   Locate the  vertex of the angle.
Step 3 :  Place the tip of the compass on the vertex of the angle and draw an arc which cuts each arm of the angle at two different points. 
Step 4 :  Place the tip of the compass on one of the points where the first arc cuts an arm of the angle.
Step 5 : Place the compass' tip on the point of intersection of the first arc and the other arm, without changing the width of the compass. 
Step 6 : Draw a line connecting the vertex of the angle and the point of intersection of the second and the third arcs.
