Question

If the radius of one circle on the sphere is r, what is the
radius of its congruent mate?

Answer 1

The radius of its congruent mate is r

Explanation:

The radius of the congruent mate of a circle on a sphere is also r. This is because all congruent circles on a sphere have the same radius.The reason behind this is that any circle on a sphere has its center as the center of the sphere. And since the sphere has a uniform radius, all the circles on it have the same radius. Hence, the radius of the congruent mate of a circle on a sphere is also r.Hence, the radius of the congruent mate of a circle on the sphere is r.
