Native American Designs Many Native American designs have geometric properties. Transformations Reflection-a figure is flipped over a line of reflection, creating a mirror image of the figure. Rotation-a figure is turned or rotated through a given angle and in a given direction about a fixed point called the center of rotation. Translation-a slide, each point of a figure is moved the same distance in the same direction. Native American Designs Symmetry Line of Symmetry-a figure has line symmetry if it can be divided by a line into two parts that are mirror images of each other. Rotational Symmetry-a figure has rotational symmetry if a turn of 180 degrees or less produces an image that fits exactly on the original figure.
