2 What is a Tessellation?It is a tiling of the plane is a collection of plane figures that fills the plane with no overlaps and no gaps
3 Types of Tessellations Regular TessellationsSemi-regular Tessellations
4 Regular Tessellations RULE #1: The tessellation must tile a floor (that goes on forever) with no overlapping or gaps.RULE #2: The tiles must be regular polygons - and all the same.RULE #3: Each vertex must look the same.There are only 2 polygons that will work for regular Tessellations and those are equilateral triangle, hexagon, and a square.
5 Semi-regular Tessellation They are made using two or more different regular polygons.
6 Tessellations and Math Tessellations use symmetry in Math.Symmetry means that at least one pattern is unchanged.There are four types of Symmetry in the plane.
7 Types of symmetry in Math RotationsTranslationsReflectionsGlide reflections
8 RotationTo rotate an object means to turn it around a point at a certain angle. This point is called the center of rotation.
9 TranslationTo translate an object means to move it without rotating or reflecting it. Every translation has a direction and a distance.
10 ReflectionTo reflect an object means to produce its mirror image. Every reflection has a mirror line. A reflection of an "R" is a backwards "R".
11 Glide ReflectionA glide reflection combines a reflection with a translation along the direction of the mirror line. Glide reflections are the only type of symmetry that involve more than one step.
12 A few uses of symmetry Patterns for shoe bottoms. Parking lot design. Design color pattern for neckties and t-shirts.Design wallpaper for interior decoration
13 How is Tessellations used in Art? First, the artist will cut out a shape and then will decide what this particular shape looks like. For example, what does this look like?
14 Tessellations and ArtThen the artist tessellated it.
15 Tessellations and ArtHe thought it looked like a house so he colored it in like this:
16 Tessellations and ArtHere is another example. What does this look like?
17 Tessellations and ArtThis is what the artist saw and how he tessellated it.
18 Tessellations and ArtYou can also take a shape, tessellate it and then color it in, like this:
19 Tessellations and ArtNow it is your turn! We are going to be doing one like the previous one we just saw. Have fun!
