Hi there, please solve it.

Will mark brainliest. when ∆rst is translated 4 units down, what are the apparent coordinates of t’?

The verbal translation for the difference of m and 7 increased by 15

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.
