WebA line of symmetry is a line that you can draw across a shape and divide it into two mirror-images. That is to say, each half of the shape is the same, but looks like its been flipped from the other. You can also think of a line of symmetry as a line that you can draw, that when you fold the shape over the line both edges would line up exactly ... WebMay 12, 2024 · What does half turn symmetry mean? rotation A half-turn means rotation by 180° a quarter-turn means rotation by 90°.
