Question

a dilation makes figures
change shape
flip
rotate
change size

Explanation:

Dilation is a transformation in geometry. It is a non - rigid transformation. The key property of dilation is that it changes the size of a figure. The shape of the figure remains the same (if the dilation factor is non - zero and real). Flipping is a reflection transformation, rotating is a rotation transformation, and changing shape would imply a non - similar transformation (but dilation gives similar figures).

Answer:

change size
