Rotation means circular movement of an object around a fixed axis. They also have n rotational symmetries about the centroid; each rotation through 2kπ/n where k is an integer running between 0 and n-1. With rotational symmetry, we can rotate around a point and come back to the exact same figure. It is also the same as "Rotational Symmetry of Order 2" Note: Point Symmetry is sometimes called Origin Symmetry, because the "Origin" is the central point about which the shape is symmetrical. The center of a shape or object with rotational symmetry is the point around which the rotation occurs. Line Symmetry and Rotational Symmetry Line Symmetry Symmetry Line symmetry means that if you take a figure or graph and reflect it, or it, over a line, the picture is going to look exactly the . Question 1 . Symmetry means balance or form.
