Maths, art and IT Symmetry Tessellation There are many different types of symetry, some of the including: Rotational symmetry Reflective symmetry The yellow line is the
line of symmetry, or the mirror line. This means that what is on one side of the line, is on the other side of the line. This hexagon has six points of rotational symmetry, each at a seperation of 60°. These points are marked by yellow dots. That is why this is an example of rotational symmetry. This is an example of reflective and rotational symmetry. This time there are only four points of rotational smmetry, with 90° seperating them. Tessellation is when a shape can fit into one another (translate), to make a 'bigger picture'. Here are some examples of tessellation: The gray square is highlighting the tessellating shape Tessellation can be found in everyday life, in brickwork, and everywhere you walk! Thank You, I hope you liked this Prezi! This is another example of reflective symmetry.
