Which term describes a transformation that turns a figure around a point by a certain angle?

• A. Rotations
• B. Reflections
• C. Translations
• D. Dilation

Answer: (A)

Turning a figure around a fixed point by a certain angle is called a rotation. In a rotation, every point moves along a circular path centered at that fixed point, so the distance from the center stays the same and the figure keeps its size and shape, only its orientation changes. The center stays in place, like a pivot, and the amount of spin is given by the angle you rotate through—whether a small turn or a full 360 degrees. This helps separate rotations from other transformations: reflections flip the figure over a line, translations slide it without spinning, and dilations change size with respect to a point. So the term that fits is rotation.
