Theorem: In the same circle or congruent circles, two arcs are____________________ if and only if their corresponding central angles are_____________________.11. By the way, “ p if and only if q ” or p ↔ q indicates a statement that is____________________________. It literally means p →q and q → p . Thiskind of statement is only true when both p and q have the same_______________ value.12.
