1.	1. Recall that two circles are congruent if they have the same radii. Prove that equalchords of congruent circles subtend equal angles at their centres.
Answer» ANSWER: Two CIRCLES are said to be congruent if and only if their radii are EQUAL. Let AB & CD are two equal CHORDS of two congruent circles with Centre O and O'. i.e AB= CD. Hence, equal chords of congruent circles subtend equal angles at their centres
