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 flipping it. But here, the orientation of the quadrilaterals has changed, so it's not a translation.
• Rotation: A rotation turns a figure around a point. The key is that the shape and size remain the same, but the position (orientation) changes. In this case, quadrilateral \(B\) is a rotated version of quadrilateral \(A\).
• Reflection: A reflection flips a figure over a line. There is no indication of a mirror - like flip (no axis of symmetry is evident in the general sense for this problem).
• Dilation: A dilation resizes a figure. The two quadrilaterals \(A\) and \(B\) appear to be of the same size.

Answer:

B. Rotation
