![]() Cut out a semi-circle and rotate it counter-clockwise.ĥ. A rotation is a bit tougher to create, but it does work well with a. Cut-out a semi-circle and rotate it counter-clockwise.Ĥ. Independent Learning you will explore some tessellations patterns on your own. Cut out a semi-circle and rotate it counter-clockwise.ģ. Cut out an equilateral triangle from a piece of paper.Ģ. You simply draw a shape or a pattern of shapes and repeat them without changing their orientation and without leaving any gaps or overlaps.Ĭomplex tessellations use more than one of the three basic operations to create a new shape that can tessellate – ie can be fit together without any gaps or overlaps.ġ. A tessellation is a tiling pattern that covers the plane without any gaps or overlaps. Simple tessellations just use the translation operation. If a reflection has been done correctly, you can draw an imaginary line right through the middle and the two parts will be symmetrical “mirror” images. Reflection is flipping an object across a line without changing its size or shape. Reflective symmetry occurs when a pattern can be folded across a mirror so one half lies on top of the other. ![]() Rotation is rotating an object about a fixed point without changing its size or shape. Rotational symmetry occurs when a pattern that we can turn a pattern by some degree about a point and the pattern looks exactly the same. Translation is sliding a figure in any direction without changing its size, shape or orientation. Here we consider the rigid motions of translations, rotations, reflections, or glide reflections. Tessellations can be created by performing one or more of three basic operations on a shape: translation, reflection and/or rotation. A regular tessellation means that the pattern is made up of congruent regular polygons, same size and shape, including some type of movement that is, some type of transformation or symmetry.
