A circle is sometimes/always/never

similar to another circle, because we can sometimes/always/never

map one onto the other using only dilations and rigid transformations.

A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.

Step-by-step explanation:

Two Circles are said to be similar if all the linear measurements of the circles are proportional.

Lets consider if  two circles have a certain ratio of their radii, , it definitely mean that  all the other corresponding ratios will also have that same ratio.

Concentric circles are defined as the  circles which have a  common center. The area between the  two concentric circles having  difference in their  radii is Known  as annulus.

The most important property of a circle is that all  points on the circle are equidistant (i.e. having the same distance) from the center point.

A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.

e) none of the above because the measure of angle cba is 101°
