Figure ABCD has vertices A(1, 1), B(1, 4), C(4, 4), and D(4, 1). What are the coordinates of the vertices of Figure A’B’C’D’ after a reflection across the line =–2 and a translation 3 units up? Drag numbers to complete the coordinates. Numbers may be used once, more than once, or not at all.

Hnmmmn not sure

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .
