A shape has Rotational Symmetry when it still looks exactly the same after some rotation less than one full turn.

Learn about the different types of symmetry: Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry), Rotational Symmetry and Point Symmetry.

Reflection Symmetry (sometimes called Line Symmetry or Mirror Symmetry) is easy to see, because one half is the reflection of the other half.

Illustrated definition of Rotational Symmetry: A shape has Rotational Symmetry when it still looks the same after some rotation. As we rotate this image we find...

A shape has Rotational Symmetry when it still looks the same after some rotation (of less than one full turn).

Point Symmetry is when every part has a matching part: the same distance from the central point. but in the opposite direction.

Here my dog Flame has her face made perfectly symmetrical with some photo editing. The white line down the center is the Line of Symmetry.

Learn about the Four Transformations: Rotation, Reflection, Translation and Resizing

Rotation means turning around a center. The distance from the center to any point on the shape stays the same. Every point makes a circle around...
