Answer: D
Step-by-step explanation:
To create a perpendicular bisector:
- open the compass more than half-way between points A and B
- use that width and place the compass on point A and draw an arc above and below line AB
- use the same width and place the compass on point B and draw an arc above and below line AB
- Draw a line from the intersection of the arcs above and the intersection of the arcs below line AB
Congrats! You just constructed a perpendicular bisector!
