Question

what is a rotation?
a sliding a figure in a straight line
b turning a figure around a fixed point
c enlarging a figure
d flipping a figure over an axis

Explanation:

To determine the correct option for "What is a rotation?", we analyze each choice:

• Option A: Sliding a figure in a straight line is a translation, not rotation.
• Option B: Rotation in geometry is defined as turning a figure around a fixed point (like the center of rotation).
• Option C: Enlarging a figure is a dilation, not rotation.
• Option D: Flipping a figure over an axis is a reflection, not rotation.

Answer:

B. Turning a figure around a fixed point
