M, O, T, V, W, X, Y 22 23 Definition of a line of symmetry: 24 Point out 3 items in the room with a line of symmetry. How do you know? A figure has line symmetry if a line can divide it into two parts that look like mirror images of each other. The two parts look alike but face in opposite directions. 23 Possible answers: computer monitor, whiteboard, blocks on wall, tiles on floor, etc 24
