Which transformation turns a figure around a fixed point by a specified angle?

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

Answer: (A)

Rotating a figure means turning it around a fixed point by a given angle. Every point swings along a circular path centered at that fixed point, staying the same distance from the center. The center itself stays in place, and the overall size and shape don’t change—the figure looks the same just turned. This is different from sliding it without turning, making it bigger or smaller, or flipping it over a line like in a mirror. Translations move the whole figure a certain distance in a straight direction. Dilations change the size of the figure. Reflections flip the figure over a line, reversing its orientation. The described action—turning around a fixed point by a specified angle—matches rotation.
