The radical axis of two circles that intersect at two points is
Atheir common secant
Btheir common diameter
Ctheir line of centres
Da common tangent
Answer & Solution
Correct answer: A. their common secant
Both intersection points have zero power in each circle, so the line through them is the radical axis.
