Shape A A\,A and shape B B\,B are drawn on a coordinate grid.
Shape A A\,A has vertices (1,2)(1, 2)(1,2), (4,2)(4, 2)(4,2), and (1,3)(1, 3)(1,3). Shape B B\,B has vertices (1,0)(1, 0)(1,0), (4,0)(4, 0)(4,0), and (1,−1)(1, -1)(1,−1).
Describe fully the single transformation that maps shape A A\,A onto shape BBB.
