Question

what single transformation was applied to quadrilateral a to get quadrilateral b?
choose 1 answer:
a translation
b rotation
c reflection
d dilation

Explanation:

• Translation: A translation slides a figure without rotating or resizing it. But here the orientation of the figure has changed, so it's not a translation.
• Rotation: A rotation turns a figure around a point. The shape and size of quadrilateral \(A\) and \(B\) are the same, but the orientation (the way the figure is turned) is different. This is characteristic of a rotation.
• Reflection: A reflection flips a figure over a line. There is no indication of a line - like a mirror - that the figure is flipped over.
• Dilation: A dilation resizes a figure. Since the size of quadrilateral \(A\) and \(B\) is the same, it's not a dilation.

Answer:

B. Rotation
