Objective 9-10 Quiz • ∆DFG has vertices D(-2, 4), F(-3, 1), and G(-1,2). Find the vertices of the image ∆D’F’G’ after a rotation of 180 O around the origin. • Judging from appearance, tell whether each figure on the board has rotational symmetry. If so, what is the angle of rotation? If not, explain. (See Mr. Maisells for these two problems.)
