Transformations By Toby Robinson

Tessellation Tessellation is when a shape can fit exactly beside itself with no gaps for an infinite distance. All polygons tessellate.

Reflection Reflection is when a shape or object is reflected over a line of symmetry. It is facing the opposite direction after it has been reflected. Original Shape Original Shape Reflection Reflection

Line of Symmetry A line of symmetry is a line in which if you fold the shape along that line the shape would fit perfectly back into itself. Lines of Symmetry: 2 Lines of Symmetry: 5

Rotational Symmetry Rotational symmetry is when a shape is rotated from 0 to 360 degrees and fits perfectly into itself. Every time it fits into itself it gets another rotational symmetry order. Every shape has a rotational symmetry order of at least 1. Rotational Symmetry Order: 5 Rotational Symmetry Order: 3

Rotation Rotation is when a shape is moved around an origin of rotation. It is normally measured in how far it has turned using degrees. Rotation of 180 degrees. Rotation of 100 degrees.

Translation Translation is the movement of shapes or objects without rotating, enlarging or reflecting. The way to record translation is vectors.

Enlargement Enlargement is making a shape or object larger or smaller through a point of enlargement or just measuring.
