Remark
The diameter of the circle is AC. The hypotenuse of the right triangle is also AC. This assumes that A,B and C all lie on the circumference of the circle.
Answers
One
The center of the circle is on the diameter of the circle. In fact, the center bisects the diameter. So the center lies on AC and if the center is labeled O then AO = BO.
<em><u>Answer 1: </u></em> AC
Two
The answer is the single word diameter.
