These problems minimize the Steiner distance and related functions. A computer is needed for 33 and.

Continuing Problem 34, there are circular arcs for all three sides of the triangle. On the arcs, every point sees one side of the triangle at a angle. Where is the Steiner point? (Sketch three sides with their arcs.)

This exercise builds on another exercise in its source book, which isn't shown here.
