This example explores experimentally the point that minimizes the sum of the squares of the distances to the three vertices of a triangle. Key concepts include triangle geometry and minimization problems. It uses commands like Segment, Ray, and Intersect in GeoGebra. Suitable for high school mathematics education and learning.
