# What is tessellation Class 9?

## Summary of the Article: Understanding Tessellation

Tessellation is a fascinating concept in geometry that involves the creation of patterns using shapes that fit perfectly together without any gaps or overlaps. It can be seen in various real-life examples such as tile floors, brick walls, and fabric patterns. Tessellations can be categorized into three types: regular tessellations, non-periodic tessellations, and three-dimensional tessellations.

Regular tessellations are those that consist of shapes such as triangles, squares, and hexagons. These shapes adhere to three essential rules: they have edges, do not create gaps, and do not overlap. On the other hand, non-periodic tessellations do not have repetitious patterns, making them more complex and unpredictable. Three-dimensional tessellations involve three-dimensional shapes like octahedrons, creating intricate patterns and structures.

Though many shapes can tessellate, circles and ovals are not among them. These shapes lack angles, and it is impossible to put them together without gaps. Regular polygons with congruent sides are more likely to tessellate, as the repetition of the same figure ensures a perfect fit.

### Questions:

**1. What are the three types of tessellations?**

There are three types of regular tessellations: triangles, squares, and hexagons.

**2. Can you provide examples of tessellations?**

Examples of tessellations include tile floors, brick walls, checker or chess boards, and fabric patterns.

**3. How do you explain tessellation?**

Tessellation is a pattern of shapes that fit together without gaps or overlaps.

**4. Are there other types of tessellations?**

Yes, non-periodic tessellations and three-dimensional tessellations exist. Non-periodic tessellations do not have repetitive patterns, while three-dimensional tessellations use three-dimensional shapes like octahedrons.

**5. What shapes cannot tessellate?**

Circles or ovals cannot tessellate due to their lack of angles and the impossibility of placing them together without gaps.

**6. What are the rules for a regular tessellation?**

A regular tessellation must have shapes with edges, no gaps, and no overlaps.

**7. Which shapes cannot tessellate?**

Circles or ovals cannot tessellate due to their lack of angles and the impossibility of placing them together without gaps.

**8. How can you determine if a shape will tessellate?**

If a figure is the same on all sides and has congruent straight sides, it is likely to tessellate when repeated.

**9. Can you provide a step-by-step process for creating a tessellation?**

To create a tessellation, use sticky notes to make each shape and prevent them from moving by adding tape to their backs.

**10. Which shape cannot tessellate?**

Circles or ovals cannot tessellate due to their lack of angles and the impossibility of placing them together without gaps.

**11. How can you determine if a shape can tessellate?**

You can draw out the shape and attempt to tessellate it, testing if it can repeat without gaps or overlaps.

**12. Which shapes always tessellate?**

The equilateral triangle, square, and regular hexagon are the only shapes that can form regular tessellations without gaps. Other tessellation possibilities exist under different constraints.

**13. What are the key features of regular tessellations?**

The key features of regular tessellations are that they consist of shapes with edges, they do not create gaps, and they do not overlap.

**14. Can you provide examples of non-periodic tessellations?**

Non-periodic tessellations are complex and lack repetitive patterns. These can be found in various artistic designs and structures.

**15. Can you give examples of three-dimensional tessellations?**

Three-dimensional tessellations involve three-dimensional shapes like octahedrons and can be observed in architectural designs and sculptures.

** What are the 3 types of tessellations **

There are three types of regular tessellations: triangles, squares and hexagons.

** What are 5 example of tessellation **

Examples of a tessellation are: a tile floor, a brick or block wall, a checker or chess board, and a fabric pattern. The following pictures are also examples of tessellations. Notice the hexagon (cubes, first tessellation) and the quadrilaterals fit together perfectly.

** How do you explain tessellation **

A tessellation is a pattern of one or more shapes that fit together with no gaps or overlaps. A tessellation can continue on a plane forever.

** Are there 2 types of tessellations **

There are two other types of tessellations which are non-periodic tessellations and three-dimensional tessellations. A three-dimensional tessellation uses three-dimensional forms of various shapes, such as octahedrons. A non-periodic tessellation is known to be a tiling that does not have a repetitious pattern.

** What shapes Cannot tessellate **

Circles or ovals, for example, cannot tessellate. Not only do they not have angles, but you can clearly see that it is impossible to put a series of circles next to each other without a gap. See Circles cannot tessellate.

** What are the 3 rules for a regular tessellation **

A tessellated plane adheres to three rules: the shapes must have edges, the shapes must not create any gaps, and the shapes must not overlap.

** Which shapes Cannot tessellate **

Circles or ovals, for example, cannot tessellate. Not only do they not have angles, but you can clearly see that it is impossible to put a series of circles next to each other without a gap. See Circles cannot tessellate.

** How do you know if a shape will tessellate **

How do you know that a figure will tessellate If the figure is the same on all sides, it will fit together when it is repeated. Figures that tessellate tend to be regular polygons. Regular polygons have congruent straight sides.

** How do you do a tessellation step by step **

Tip number one use sticky notes to make each shape of your tessellation. Another tip to keep it from moving around just take some tape roll. It up like. So stick. It on the back.

** Which shape Cannot tessellate **

Circles or ovals, for example, cannot tessellate. Not only do they not have angles, but you can clearly see that it is impossible to put a series of circles next to each other without a gap. See Circles cannot tessellate.

** How do you tell if a shape can tessellate **

The best way to approach these problems is to actually draw out the shape and see if you can tessellate it so attempt to test later okay we can do that with a very first option here so option number

** Which shapes always tessellate **

There are only three shapes that can form such regular tessellations: the equilateral triangle, square and the regular hexagon. Any one of these three shapes can be duplicated infinitely to fill a plane with no gaps. Many other types of tessellation are possible under different constraints.

** How do you know if a shape can tessellate **

How do you know that a figure will tessellate If the figure is the same on all sides, it will fit together when it is repeated. Figures that tessellate tend to be regular polygons. Regular polygons have congruent straight sides.

** What are the rules for a shape to tessellate **

In a tessellation, whenever two or more polygons meet at a point (or vertex), the internal angles must add up to 360°. Only three regular polygons(shapes with all sides and angles equal) can form a tessellation by themselves—triangles, squares, and hexagons.

** What are the 4 rules for creating a tessellation **

TessellationsRULE #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.

** What only 3 shapes can tessellate **

Only three regular polygons(shapes with all sides and angles equal) can form a tessellation by themselves—triangles, squares, and hexagons.

** What shape Cannot be tessellated **

** How do you tell if a shape will tessellate **

How do you know that a figure will tessellate If the figure is the same on all sides, it will fit together when it is repeated. Figures that tessellate tend to be regular polygons. Regular polygons have congruent straight sides.
