the construction of creating the perpendicular bisector of PQ is started below. How would the construction be different if you changed the compass setting in the next step of the perpendicular bisector construction?

A perpendicular bisector divides a line segment into two equal segments.

If the compass setting is changed, the line will not be bisected.

To bisect a line, the positioning of the compass must be done as follows:

The above points are what is being done in the given construction.

Any step or setting other than that, would not create a perpendicular bisector.

Hence, if the compass setting is changed, the perpendicular bisector of the line would not be drawn.

 It will not create a perpendicular bisector.

Explanation:

If the compass is the same setting as the first arc and drawn from point B, the points of intersection of the arcs will pass through the midpoint of AB (thus creating a perpendicular bisector).

If you change the setting of the compass and draw an arc from point B, the points of intersection of the arcs will still create a perpendicular line but will not pass through the midpoint of AB (creating a perpendicular line but not a perpendicular bisector).

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
