Chords in Circles and Arc Length

If AB and CD are two chords of a circle intersecting at point E, as per the given figure. Then:

• ∠BEQ > ∠CEQ

• ∠BEQ = ∠CEQ

• ∠BEQ < ∠CEQ

• None of the above

If the angles subtended by two chords of a circle or of congruent circles at the centre are equal, the chords are ——–

• equal

• unequal

• different

• none of above

In the figure, if O is the centre of a circle, then the measure of ∠ACB is:
