If a point is equidistant from the endpoints of a segment, then it is:
a. the midpoint of the segment.
b. on the angle bisector of the segment.
c. on the perpendicular bisector of the segment.
d. on the segment.

C

Step-by-step explanation:

A point equidistant from the endpoints of a segment not necessarily is on the segment, then, options A and D are discarded (the midpoint of the segment is on the segment). The angle bisector divides an angle in two equal angles, and is not applied to a segment; then, option B is discard. The perpendicular bisector of a segment divide a segment in two equal parts, then, all of its points are equidistant from the endpoints of the divided segment.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
