Ineed with rewriting radicals by extracting all perfect squares.

the problem:
√144

Ineed asap. i cant understand this question i need someone to me right away

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.

Typically a point in a three dimensional cartesian coordinate system is represented by which of the following answers in the picture !
