The medial triangle of a triangle ABC is the triangle with vertices at the midpoint s of the triangle s sides AB, AC and BC. The medial triangle is different from the median triangle . Clarification needed date February 2011 The medial triangle can also be viewed as the image of triangle ABC transformed by a homothety centered at the centroid with ratio 1 2. Hence, the medial triangle is inversely Similarity geometry similar and shares the same centroid and median geometry medians with triangle ABC .
