Question

question 2 of 2
select the correct answer.
what is a rotation?
a rotation is when an object moves in a circular arc around a point.
in a rotation, each point in the preimage and its corresponding point in the image are at equal distances from a given line. also, the line segment joining two such points is perpendicular to the given line.
a rotation is when an object moves a specified distance along a line parallel to a specified line.
a rotation proportionally stretches or compresses an object based on a given scale factor.

Explanation:

To determine the correct definition of rotation, we analyze each option:

• The first option: A rotation is when an object moves in a circular arc around a point. This matches the geometric definition of rotation (turning a figure around a fixed point).
• The second option describes a reflection (points equidistant from a line, line segment perpendicular to the line).
• The third option describes a translation (moving along a line parallel to a specified line).
• The fourth option describes a dilation (stretching/compressing based on a scale factor).

Answer:

A. A rotation is when an object moves in a circular arc around a point.
