Creating a perpendicular bisector of a segment AB using only an unmarked straightedge and an unmarked compass requires a step-by-step process. Here is how you can achieve this:

Step 1: Draw two circles with the same radius from points A and B. To do this, place the compass on point A and draw an arc that intersects the segment AB. Keep the compass at the same width and place it on point B, drawing another arc intersecting the segment AB. Label the points of intersection as C and D, respectively.

Step 2: With the compass set at a width greater than CD but smaller than AB, place the compass on point C and draw an arc above and below CD. Similarly, place the compass on point D and draw arcs above and below CD. Label the points of intersection between the arcs above and below CD with points E, F, G, and H, respectively.

Step 3: Now, bring your straightedge and connect the points E and G. Also, connect the points F and H. These two lines will intersect at point O, which is the midpoint of segment CD.

Step 4: With the compass still set to the width that was used in Step 2, place the compass on point O and draw arcs both above and below EF. These arcs need to intersect the lines connecting points E and G and F and H, respectively. Label the points of intersection with I and J, respectively.

Step 5: Finally, using your straightedge, draw a line through points I and J. This line will be perpendicular to AB and will bisect it at point O.

By following this process, you have successfully created the perpendicular bisector to segment AB using only an unmarked straightedge and an unmarked compass.
