<span>Use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.
</span>Mark an arc through the sides of the angle. Let the arc intersect the rays at A and B. Continue the arc on past B for a distance.
<span>Set the compass at B, and to the width of AB. </span>
<span>Still with the compass at B, mark an arc to intersect the first arc at C. </span>
<span>Now you have AB = BC. </span>
<span>Since the radius OA=OB=OC, angles AOB and BOC are congruent.</span>
