Line Symmetries Mathematically, a geometric figure has a line of symmetry ℓ if it is its own image under a reflection in ℓ.

Rotational (Turn) Symmetries A figure has rotational symmetry, or turn symmetry, when the traced figure can be rotated less than 360° about some point, the turn center, so that it matches the original figure.
Point Symmetry Any figure that has rotational symmetry 180° is said to have point symmetry about the turn center.
