Question

How would the construction be different if you changed the compass setting in step 4 of the perpendicular bisector construction?

Answer 1

If the compass angle is changed, the entire geometric shape being drawn is different. For example, if a triangle is being drawn, it could change from an obtuse triangle from a ninety degree triangle.

Answer 2

A bisecting line could not be drawn.

Explanation:

If the compass width was changed, then we could not trace a bisecting line. Different arc measures would not intersect each other, at the center.

So, we would not be able to trace a bisecting line. We would have something like the picture below.
