A figure, picture, or pattern has symmetry when its parts match in size and shape across a line, so one side can be seen as a reflection of the other; the line may be vertical or horizontal. Learners identify and describe familiar examples, including figures that do not match symmetrically, without yet analyzing rotational symmetry, formal transformations, or symmetry in complex shapes.
Symmetry means that two parts of a picture match like a reflection in a mirror. The matching line can go up and down or side to side.
Example: Does a butterfly have symmetry?
So, the butterfly has vertical symmetry. Its left side is a reflection of its right side.
