All side lengths in quadrilateral PQRS measure 4 units. A transformation maps PQRS to P′⁢Q′⁢R′⁢S′. All sides of P′⁢Q′⁢R′⁢S′ measure 1 unit. Is the transformation an isometric transformation? Explain.

An isometric transformation preserves distances, so corresponding side lengths must stay the same. Here, each side changes from 4 units to 1 unit, so the side lengths are not preserved. Therefore, the transformation is not isometric; choice D is correct.
