## Content Summary

Euler gives us three points, *A*, *B*, and *C*, the distances between them, and that they are centers of circles of radius *a*, *b*, and *c* respectively. He finds a point *O*, the center of a circle, and the radius *x* of that circle, such that the circle is tangent to each of the three given circles.
