Symmetry

There are two types of symmetry that you should know:  Reflectional Symmetry Rotational Symmetry
• A figure has reflectional symmetry or symmetry about a line if reflection across the line produces an identical figure.
• A figure has rotational symmetry or symmetry about a point P is a rotation of k degrees, 0<k<360, clockwise or counterclockwise, about P produces an identical figure.
Note that the figure on the left does not have symmetry about a point, and the figure on the right does not have symmetry about a line. Many of figures, however, have both types of symmetry.

A figure has reflectional symmetry or symmetry about a line if a line can be drawn through it, dividing it into two parts that are the same but facing in opposite directions. Is the dotted line a line of symmetry? Yes
No
