Two arcs are congruent if their measures and radii are equal.
Question 1 Recall that two circles are congruent if they have the same radii. Prove that equal chords of congruent circles subtend equal angles at their centres.
Consider the following statements and choose the right option.
Statement 1: If two arcs are congruent, then their corresponding chords may not be equal.
Statement 2: If the angles subtended by two chords are equal, then the corresponding arcs are congruent.
