Final answer:
To find the transformation from figure A to B, one must know the traits of translations, rotations, reflections, and dilations and compare them.
Step-by-step explanation:
To determine the transformation used to change figure A to figure B, we need to understand the characteristics of each type. A translation involves sliding the entire figure to a different location without changing its size or orientation. A rotation involves turning the figure around a fixed point, known as the center of rotation. A reflection is like looking in a mirror; the figure gets flipped across a line. Lastly, a dilation is a scaling transformation that changes the size of the figure while keeping its shape the same.
