Congruent Circles Definition.
Congruent Circles.
Congruent circles can be defined as circles that have equal radii.
For example:
The above two circles with centers P and Q have equal radii of r units each.
Hence, these two circles are congruent circles.
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.
Congruent circles that have congruent central angles have
