Prove that if chords of congruent circles subtend equal angles at their centers then the chords are equal?

let the two circles with centre O and P are congruent circles, therefore their radius will be equal. given: AB and CD are the chords of the circles with centres O and P respectively. ∠AOB=∠CPD TPT: AB=CD proof: in the ΔAOB and ΔCPD AO=CP=r and OB=PD=r ∠AOB=∠CPD therefore by SAS congruency, ΔAOB and ΔCPD are congruent triangle. therefore AB=CD

If two circles have the same point then what are they called?

If you mean they both have the same centre - they're called 'concentric' circles.


Is concentric circle and congruent circle are they same?

No. Concentric circles have the same centre but not [usually] the same radius. Congruent circles have the same radius, but not [usually] the same centre. If you have two concentric congruent circles one will be exactly on top of the other.

What is the diffrerence between concentric and eccentric circles?

Concentric circles are circles that share the same center point, with each circle surrounding the other. Eccentric circles, on the other hand, do not share the same center point and are offset from each other. In simpler terms, concentric circles are like a target with multiple rings around a common center, while eccentric circles are like two circles that are not aligned at the same center point.


Do circles have the same center?

No not all circles have the same centre. If the circles formula is in the form x2+ y2=r2 then the centre is always the origin= (0,0). But if the formula for the circle is in the form (x-h)2+(y-k)2= r2 then the centre is the the opposite sign of the h and the k. Eg. (x+4)2+(y-9)2=16 the centre would be (-4,9) and the radius would be 4
