In a recent study, mathematicians from Freie Universität Berlin have demonstrated that planar tiling, or tessellation, is much more than a way to create a pretty pattern. Consisting of a surface ...

Translations and reflections are examples of transformations of shapes. If a shape is transformed, its position and/or size is changed. Translation is when a shape slides across, up, down or ...
