circle S and circle U are congruent circles.

A. name the three radii of circle S.
B. name the three radii of circle C.
C. How are the radii of the two circles related? Explain your reasoning.

I assume there are some points labeled around the circumference of the circles.

Any line from the center to the circle is a radius.

circles are congruent, so all features are identical.

A. The three radii of circle S can be named as RS, ST, and SR.

B. The three radii of circle C can be named as CU, CT, and CR.
C. The radii of the two circles (S and U) are congruent. This means that they have the same length. So, for example, RS in circle S is equal to RU in circle U, and ST in circle S is equal to UT in circle U. The radii of the two circles are related by their equality in length, making them congruent.

To answer these questions, we need to understand the concept of radii in circles. The radius of a circle is a line segment that connects the center of the circle to any point on its circumference. In this case, let's assume circle S and circle U are congruent circles.

A. To name the three radii of circle S, we first need to find the center of circle S. If we know the coordinates of the center, we can then draw radii from the center to three different points on the circumference of the circle. Without more information, it is not possible to determine the specific radii of circle S.

B. Similarly, to name the three radii of circle U, we would need to know the coordinates of the center of circle U. Once we have the center's coordinates, we can draw radii from the center to three different points on the circumference of the circle. Without additional information, it is not possible to determine the specific radii of circle U.

C. Since circle S and circle U are congruent circles, it means that they have the same size and shape. Consequently, their radii must also be congruent. In other words, if we were to measure the length of any radii in circle S, it would have the same length as the corresponding radii in circle U. The relationship between the radii of the two circles is that they are equal in length due to the circles being congruent.
