Angle Bisector
Step 1: Form an angle using two rays, and name it angle BAC
Step 2: Use your compass, and draw a circle with the center being point A
Step 3: Now where the circle crosses ray AB put a point, and call it point D
Step 4: Where the circle crosses ray AC put a point, and call it point E
Step 5: Now using your compass, make an arc with in the angle from point D
Step 6: Make a arc from point E that intersect point D's arc
Step 7: Put a point at the intersection of E and D's arcs, and call it point H
Step 8: Draw a ray from point A that goes through point H
Your angle BAC will be perfectly bisected into two equal angles.
