Triangle mno is dilated to create triangle pqr on a coordinate grid. you are given that angle n is congruent to angle q. what other information is required to prove that the two triangles are similar?

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
