We plan to construct a line segment through point p and perpendicular to line segment ef. what is the smallest number of compass adjustments with which this can be done? a) 1 b) 2 c) 3 d) 4

A) 1

Step-by-step explanation:

REmember that to create the perpendicular line segment to the segment EF you just have ot adjust the compass to three quarters and draw semi circular segments from points E and "F" that would intersect with eachother and from there to the other side of the segment you draw a line fomr the two points where the semi circles intersect with eachother. so you only need one adjustment to the compass.
