Which pair of complex numbers has a real-number product?
(1 + 3)(61)
(1 + 31)(2-31)
(1 + 31)(1 – 3)
(1 + 3)(31)

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.
