9.6 Identify Symmetry Mrs. vazquez Geometry

g.co.3 Essential Question: What type of symmetry does the figure have? Objective: Students will be able to identify line and rotational symmetry of a figure.

line symmetry A figure has line symmetry if it can be mapped onto itself by a reflection in a line. A figure may have 1+ lines of symmetry.

lines of symmetry

rotational symmetry A figure has rotational symmetry if it can be mapped onto itself by a 180o or less rotation.

Does it have rotational symmetry?
