Quаdrilаterаl ABCD is rоtated abоut the оrigin and translated 3 units up. Give the coordinates of the resulting congruent quadrilateral A"B"C"D". A" ([ans0],[ans1]) B" ([ans2],[ans3]) C" ([ans4],[ans5]) D" ([ans6],[ans7]) The coordinate grid spans from just below negative one to eight on the x-axis and from below negative 2 to above 7 on the y-axis. Both axes are scaled in increments of 1. Quadrilateral ABCD is plotted on the coordinate grid. The vertices are labeled A at (1, 1), B at (3, 4), C at (8, 3), and D at (4, 3). The four vertices are connected by line segments AB, BC, CD, and DA, forming an irregular four-sided shape
