Maya: "Hannah and Maya, make some nature in a pattern using reflective ... way round you look at them. This kind of symmetry is called rotational symmetry. Rotational symmetry is where a shape ...

Biot's conjecture at the time — that optical activity is associated with molecules of low rotational symmetry — was later confirmed by Louis Pasteur. The molecules responsible for optical ...

The number of lines of symmetry in a regular polygon is equal to the number of sides. A shape has rotational symmetry when it can be rotated and it still looks the same. The order of rotational ...
