Are circles with the same center always the same size?
a) yes, if they have the same center then they are the same circle.
b) no, it is not possible for two circles to be the same size with the same center.
c) sometimes, if they have the same center and the same radius length they will be the same size.
d) sometimes, if they have the same center and the same chord length then they will be the same size.

Option C. sometimes, if they have the same center and the same radius length they will be the same size

Step-by-step explanation:

we have two cases

First case) Two circles of the same center and same size (length of radius)

example

Center ,

Center ,

Second case) Two circles of the same center, but different size (length of radius)

example

Center ,

Center ,

therefore

sometimes, if they have the same center and the same radius length they will be the same size

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
