Question
Rotations preserve distances from the _____
- Origin
- Centre of rotation
- Line of reflection
- X – axis
Hint:
In rotation, figure is turned through a specific angle.
The correct answer is: Centre of rotation
A rotation is a transformation that rotate every point of a figure through a specified angle and direction about a fixed point. The fixed point is called the centre of rotation.
So, rotations make figure turn in a cycle around centre of rotation. Hence, the distance of each rotated point from the centre remains the same i.e. only the relative position changes.
