Three lines labeled as a, b, and c inside a triangle.

This is an equilateral triangle. Can you find all points x in the triangle that minimize the sum a + b + c of the distances a, b, c of x from the three sides of the triangle? (Image apadted by MIT OpenCourseWare from Supplementary Problems #3 (PDF).)
