1. Carefully prove the theorem: The sum of the distances from any interior point P to the sides of an equilateral triangle is equal to the length of the triangle's altitude. Hint: Begin by partitioning AABC into three triangles based on the interior point P. Then express the area of AABC as the sum of the areas of these three internal ones. Conclude that the height of AABC is 1+m+n. n m
