We have the following:
It is a movement around a point that maintains the shape and size of the original figure. A rotation is determined by these three elements:
0. An angle that determines the amplitude of the rotation.
,
1. A point called the center of rotation.
,
2. A direction of rotation that can be clockwise or counterclockwise.
Therefore, the answer is:
Each point on the original figure is the same distance from the center of rotation as its image. All angles formed by a point and its image, with the vertex at the center of rotation, are congruent
