To create a perpendicular bisector to a segment AB using only an unmarked straightedge and an unmarked compass, follow these steps:
1. Place the compass needle on point A and draw an arc that intersects the line segment AB. Keep the compass needle fixed at this point.
2. Without changing the compass width, place the compass needle on point B and draw another arc that intersects the line segment AB. Make sure the new arc intersects the previous arc you drew.
3. Without changing the compass width, place the compass needle on one of the intersection points of the two arcs and draw arcs on both sides of the line segment AB.
4. Using the straightedge, draw a straight line that connects the two intersection points of the arcs. This line should intersect the line segment AB.
5. Extend the line segment beyond the points where it intersects the line segment AB.
6. Using the compass, place the needle on one of the points where the extended line segment intersects the line segment AB.
7. Without changing the compass width, draw an arc that intersects the extended line segment on both sides.
8. Repeat step 7, but this time place the compass needle on the other point where the extended line segment intersects the line segment AB.
9. The intersection point of the two new arcs is the midpoint of the line segment AB.
10. Using the straightedge, draw a line that passes through this midpoint and is perpendicular to the line segment AB.
Now you have successfully created the perpendicular bisector to the segment AB using only an unmarked straightedge and an unmarked compass.
Describe a process you would use to create the perpendicular bisector to a segment AB using only an unmarked straightedge and an unmarked compass.
