17.2 Rotational symmetry and transformations
Rotational symmetry and transformations
When an object is turned around its center of rotation to certain degrees and the object looks the same, we can say it has rotational symmetry. We will learn the details of rotational symmetry including, lines of symmetry, order of rotation, and angle of rotation.
