Similarity can be proved using similarity criteria. We know the lengths of the sides, so we will use them. BC refers to BD as BD to AD. Similarity coefficient = 0.5. The proof lacks equality of angles. Angle ABD = Angle CBD, with secant BD. The triangles CBD and BDA are similar in the second characteristic of similarity.
