Which lines are perpendicular to the line y - 1 = {(x+2)? Check all that apply. O y +2=-3(x-4)
y-5= 3(x + 11)
y=-3x - 5
Ov-4-2
3x + y = 7

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.
