Which sequence of transformations maps Figure A to Figure B? Graph where both the axes run from minus four to plus four and beyond. Figures A and B are two traingles drawn in the first and the fourth segment of the graph. The coordinates of A are (2, 2), (4, 3) and (3, 4). The coordinates of B are (1, -3), (2, -5) and (3, -4).

A- A reflection across the x-axis, and then a translation 1 unit down and 1 unit left

B- A reflection across the y-axis, and then a translation 1 unit down and 1 unit left

C- A reflection across the x-axis, and then a translation 2 units down and 1 unit left

D- A 270° rotation about the origin, and then a translation 2 units down and 1 unit left

option: d is the correct answer.

          d.) triangle cde.

step-by-step explanation:

since, in δead and δcde we have:

∠ead≅∠cde (as the measure of both the angles are equal as both   are right angles)

also ∠dea≅∠dec (as both the angles are same)

hence, by aa similarity we state that δead and δcde are congruent.

      hence, option: d is the answer.
