A. True

B. False

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.

Based on the diagram above, a student determined the hypotanuse of the triangle to be 6√3. determine if the students answer is correct. if not correct find the correct length
