Unfortunate to us these two triangles are not necessarily equal to each other. Thus to proof ourselves we need to use the mathematics theorem by using the ratios. We will have to construct the set of triangles these types.

If we continue the angle bisector line keep going from D and draw a line parallel to AB and create a line from C and name it as F. Thus, FC parallel to AB. This way we can look like two triangles look similar.

So BC must be the same as FC. Thus we know that in a triangle when two angles are similar the third one also become same. Thus angle bisector of an angle in a triangle which separates the opposite side in the same ratio as the sides adjacent to the angle.
