If a triangle within a triangle has base lines that are parallel, the two triangles MUST be similar because their three angles are all congruent. Angles D and B as well as E and C are congruent because they are corresponding angles on parallel lines. Angle A is a reflexive angle.

Since the triangles are similar that means the corresponding sides must be:
