Final answer:
A perpendicular bisector construction results in the perpendicular bisector itself, which is a line that divides another line into two equal parts at a 90° angle.
Step-by-step explanation:
The shape that can be made from the perpendicular bisector construction is the perpendicular bisector itself. This is because the process of constructing a perpendicular bisector involves drawing a line that is perpendicular (forming a 90° angle) to a given base line and bisecting it, which means it divides the line into two equal parts at its midpoint. The construction does not involve creating a closed shape like a circle, square, or triangle, but rather just the line that bisects another line perpendicularly.
