Question

What kind of triangle appears to be formed

if one of two circles has a radius twice as long as the other how do the circumference compare.

Answer 1

What is the radius of a circle around a triangle?

It also illustrates a situation where different methods can lead to what appear to be entirely different answers, yet they may be identical. A circle O is circumscribed around a triangle ABC, and its radius is r. The angles of the triangle are CAB = a, ABC = b, BCA = c.
