Question

two circle are congruent if they have the same:

(b) radius
(c) centre and radius
(d) none of these
​

Answer 1

Answer:

RADII !

Step-by-step explanation:

I am 100% sure about this one.This makes sense too.

If two circles have equal radius,they will have the same shape.

If the two circles have the same centre and radius,they would be the same circle.

If the two circles have only same centre,then one circle may be bigger than the other and hence they would not be congruent!

Answer 2

According to the Euclids book two circle are congruent with any centre and radius
