15) Which coordinate pair identifies a point in Quadrant III of the coordinate plane? A) (2,3)

B) (-2,3)

C (2, 3)

D (-2, -3)​

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.
