Question

which diagram shows quadrilateral stuv rotated 120° counterclockwise about t?

Explanation:

Step1: Identify rotation center

The rotation center is point \( T \), so \( T \) remains fixed in the rotated figure.

Step2: Check 120° counterclockwise rotation

A 120° counterclockwise rotation about \( T \) should shift vertices like \( S, U, V \) to positions where the angle between \( T \) and each original/rotated vertex is 120°, and side lengths remain equal. The upper diagram shows this correct angular shift and preserved lengths.
