# Again With The Tangent Circles?

Consider the following circles: \(\Gamma_1\) is centered at \((1,0)\) with radius 1, \(\Gamma_2\) is centered at \((-1,0)\) with radius 1, and \(\Gamma_3\) is centered at \((0,4)\) with radius 2.

Now consider all circles that are tangent to \(\Gamma_1\), \(\Gamma_2\), *and* \(\Gamma_3\). Find the sum of the *distinct* curvatures of these tangent circles.

**Details and assumptions**

- The
*curvature*of a circle is the reciprocal of its radius. - We are only summing
*distinct*curvatures, so if there are two circles with the same curvature, only add their curvature once.
