# How do you put 3 regular pentagons together?

Regular pentagons do not tessellate.

### What shape can tessellate with a regular pentagon?

hexagons work because each angle is 120 degress, as you say, and 3 times 120 equals 360 degrees. So three hexagons will surround a point with no 'space" left over. but the interior angle of a pentagon is108 degrees. three pentagons together only fill up 3 time 108, or 324 degrees. There is space left over. But four pentagons would overlap. so 3 is not enough and 4 is too many. Pentagons cannot surround a…

### Why cant a regular pentagon be used to create a regular tessellation?

it can tessellate * * * * * NO IT CANNOT! A regular polygon can be used to create a regular tesselation if and only if its interior angle divides 360 degrees. The interior angle of a regular pentagon is 108 degrees, which does not divide 360 degrees so it cannot be used for a regular tesselation. . Three pentagons meeting at a point would cover 3*108 = 324 degrees - not enough to cover…

### Why are there only 5 regular polyhedra?

understand you need at leas 3 faces per corner to make a 3d object and all shapes on a regular polyhedron must be regular. triangles: tetrahedron,(3 per corner) octohedron,(4 per corner) icosahedron,(5 per corner) there is none with 6per corner because that would be 2d as all shapes must be regular squares: cube(3 per corner) is the only one because 2 or 4 would both be 2d. pentagons: dodecaahedron(3 per corner) is the only one…

### What shape can be used to create a regular tessellation?

All triangles will tessellate. All quadrilaterals will tessellate There are 15 classes of convex pentagons (the latest discovered in 2015) which will tessellate. Regular hexagons will tessellate. In addition, there are 3 classes of irregular convex hexagons which will tessellate. No convex polygon with 7 or more sides will tessellate.

### Can irregular polygons tessellate?

Some can, but not all. For example, rhombi, rhomboids, oblongs, and isosceles triangles can tessellate; however, most irregular polygons cannot. * * * * * True, but an incomplete answer. All triangles and quadrilaterals, whether regular or irregular, will tessellate. No regular pentagon will tessellate but (as of 2016), there are 15 irregular pentagons which will tessellate. There are 3 convex hexagons, (regular and 2 irregular) which will tessellate. No polygon with 7 or more…

### What are regular and irregular solids?

A regular solid is also called a platonic solid. It is a solid whose faces are identical regular polygons. There are 5 such solids. There are only 5 of them because a regular solid has 3, 4 or 5 regular polygons meeting at a vertex. If you look at the maximum number of angles you can see why there are exactly 5 platonic solids. The 5 platonic solid are: Tetrahedron where 3 triangles meet at…

### Which of the polygons cannot be used to create a pure tessellation?

The only regular polygons which will tessellate are those with 3, 4 or 6 sides. But all irregular triangles, all irregular quadrilaterals, 15 classes of irregular convex pentagons and 3 classes of irregular convex hexagons will tessellate. In addition, there are concave polygons with different numbers of sides which will also tessellate.

### What is the angle relationship in a tessellation?

There is no general relationship. All triangles will tessellate. All quadrilaterals will tessellate There are 15 classes of convex pentagons (the latest discovered in 2015) which will tessellate. Regular hexagons will tessellate. In addition, there are 3 classes of irregular convex hexagons which will tessellate. No convex polygon with 7 or more sides will tessellate.

### What type of polygon is needed to make a tessellation?

### Why do some pentagons tile a plane while others don't?

The interior angle of a regular pentagon is 108 degrees. Three such angles make 324 degrees while four make 432 degrees. It is not possible to cover 360 degrees without gaps or overlap. So regular pentagons cannot tessellate. However, irregular pentagons can. Their angles must be such that they can meet 3 or 4 at a time and, between them, cover 360 degrees. This constrains the values that the angles can have. Also, in most…
