    they would only be congruent if the triangle were equilateral or isosceles where side BC would be the base or dissimilar side. triangles ABDA and ACDA are always equal because 1/2 x b x h or the area of any triangle is exactly twice 1/2 x (0.5)b x h the area of either half.

  • The height stays constant, and the base is halved by definition of median.
