Question

which description is true about the transformation shown? it is a dilation because the transformation is isometric. it is a dilation because the transformation is not isometric. it is a stretch because the transformation is isometric. it is a stretch because the transformation is not isometric.

Explanation:

Isometric transformations preserve shape and size. Dilation changes the size of a figure (scaling). Here, the dimensions of the trapezoid have changed proportionally (sides are doubled). A dilation is a non - isometric transformation. A stretch is a transformation that changes the shape in a non - proportional way in one or more directions, which is not the case here as the figure is uniformly scaled.

Answer:

It is a dilation because the transformation is not isometric.
