This example demonstrates constructing an inner triangle by marking trisection points on each side of triangle ABC and connecting vertices to the trisection points on opposite sides. The three connecting lines intersect to form a smaller interior triangle GHI. Using GeoGebra's dynamic construction, users can measure area ratios, interior angles, and centroids of both triangles, visually exploring
