Polygon ABCD has the following vertices: Al-5, 4), B(1,4), C(6,-4), and D(-5, -4)
Calculate the area of the polygon.

a.48 units squared
b. 53 units squared
c. 68 units squared
d. 88 units squared

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.
