Rotation Symmetry Extension
A figure has rotational symmetry if, when it is rotated (turned) less than 360° around a central point, it coincides with itself (Looks exactly the same) • The central point is called the center of rotation. • A figure that coincides with itself after a rotation of 180° has rotational symmetry
Tell how many times each figure will show rotational symmetry within one full rotation. Draw lines from the center of the figure out through identical places in the figure. Count the number of lines drawn. The figure will show rotational symmetry 4 times within a 360° rotation.
Tell how many times each figure will show rotational symmetry with one full rotation. Draw lines from the center of the figure out through identical places in the figure. Count the number of lines drawn. The figure will show rotational symmetry 3 times within a 360° rotation.
Insert Lesson Title Here Tell how many times each figure will show rotational symmetry within one full rotation. Draw lines from the center of the figure out through identical places in the figure. Count the number of lines drawn. The figure will show rotational symmetry 4 times within a 360° rotation.
Degree of Rotation • The smallest number of degrees that a figure can be turned and still look identical to itself. Trace the following figure. Rotate the figure and determine the degree of rotation (what degree does it start looking identical to the original?)
Finding the Degree of Rotation Can be found by: 360° ÷ # of lines of symmetry
