Geometry!

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.

prove δabc ≅ δgfe.

! this is what i have so 's not much !

∠dec ≅ ∠dce (given)
∠dec = ∠gef (angle-angle (aa) similarity)
