Answer:
D
Step-by-step explanation:
The relantionship is perpendicular, because when you do the procedure that the question talks about, you find a circumference, and A and B are points of that cirumference.
As the segment is her diameter, we know that they, the points A and B, are perpendicular to the segment.
Why?
Because the definition of a circumference is:
> A single point in a bidimensional space that has the same distance from a infinity amount of points - remember that a point has no dimension, so there is infinity points over one point -, what became to be a circumference.
Also, take note that the lower distance for any point is a straight segment, who is perpendicular for both points.
But talk maybe do not help. Look the annex.
