Answer: choice D) translation 6 units to the right
The black triangle slides over 6 units to the right to line up perfectly with the blue triangle. In other words, every point on triangle A will slide over 6 units to the right to line up with its corresponding point on triangle A'. Both triangles are congruent (same shape and size).

Step-by-step explanation:
so we have three points, A, B and C, if indeed AC is the diameter of the circle, then half the distance of AC is its radius, and the midpoint of AC is the center of the circle, morever, since B is also on the circle, the distance from B to the center must be the same radius distance.
in short, half the distance of AC must be equals to the distance of B to the midpoint of AC, if indeed AC is the diameter.

now, let's check the distance from say A to the center, and check the distance of B to the center, if it's indeed the center, they'll be the same and thus AC its diameter.
