Answer:
Yes, Q is the center of the circle
Step-by-step explanation:
To answer this we need to know what is a circle and some of its components:
(1) The circumference is a curved line of equidistant points to a point Q called center. There is infinitive equidistante points.
(2) The diameter is any segment that joins 2 points of the circumference through the center.
So, if there are points A, B and such that the distances QA,QB and QC are identical, (1) and at least 2 different diameters of the circle contain point Q (2), then, point Q is the center.
