Unformatted text preview: the measure of the acute or right angle formed by the intersecting lines of reflection. '' APA ∠ Corollary 9.1 • Reflecting an image successively in two perpendicular lines results in a rotation. 180 o Rotational Symmetry • If a figure can be rotated less than 360 degrees about a point so that the image and the preimage are indistinguishable, then the figure has rotational symmetry . • A rotation about point O through 180 o is called a halfturn and is denoted by H O . The hexagon has rotational symmetry of order 6 and a magnitude of 60 degrees. Joke Time • Why wouldn’t they let the butterfly into the dance? • Because it was a moth ball. • What happened when the chicken slept under the car? • She woke up oily next morning....
