Shapes tessellate to fit around an interior angle. They also tessellate because they are regular polygons; non-regular polygons cannot tessellate. * * * * * Not correct. All triangles and quadrilaterals will tessellate, whether regular or irregular. Contrary to the above answer, a regular pentagon will not tessellate but there are 14 different irregular pentagons which will tessellate (the last was discovered in 2015). Three convex hexagons will do so as well. No polygon of 7 or more sides will tessellate - whether they are regular (contrary to the above answer) or irregular.
Most regular polygons will not tessellate but if their interior angles is a factor of 360 degrees then they will tessellate or if their angles around a point add up to 360 degrees then they also will tessellate.
A regular octagon does not tessellate because the interior angles of a regular octagon, which measure 135 degrees, cannot perfectly fit together without leaving gaps. When attempting to tile a plane with regular octagons, the angles do not sum to 360 degrees around a point, making it impossible to cover a surface without overlaps or spaces. In contrast, shapes like equilateral triangles, squares, and hexagons can tessellate since their angles can combine to meet the necessary conditions for tiling.
When a regular polygon can tessellate, it can be placed around a point (which has an angle of 360 degrees) with no 'space' left over. However some regular polygons don't tessellate because their interior angle is not a factor of 360 (does not go into 360 equally), meaning that there will be 'space' left over or it will overlap. To check if a regular polygon can tessellate, see if it's interior angle goes into 360 equally. (360/interior angle), if it does, it will tessellate and if it doesn't it's because the interior angle is not a factor of 360 meaning it will not fit round a point and won't tessellate.
For a shape to tessellate, it must meet certain conditions: the angles of the shape must fit together without gaps or overlaps, which means the sum of the angles around a point must equal 360 degrees. Additionally, the shape must be able to cover a plane entirely when repeated in a pattern. Regular polygons like equilateral triangles, squares, and hexagons can tessellate, while others, like regular pentagons, generally cannot without specific modifications. Lastly, shapes can also tessellate if they are irregular, as long as they meet the angle and coverage criteria.

A regular heptagon does not tessellate because its internal angle is approximately 128.57 degrees, which does not divide evenly into 360 degrees. For a shape to tessellate, the angles must combine perfectly to fill the space around a point without gaps or overlaps. Since the angles of a heptagon cannot satisfy this requirement, they cannot create a repeating pattern that covers a plane without leaving empty spaces.
No, a tessellation cannot be created using only regular pentagons. This is because regular pentagons do not fit together to fill a plane without leaving gaps or overlapping. The internal angles of regular pentagons (108 degrees) do not allow for combinations that sum to 360 degrees around a point, which is necessary for a tessellation. Other shapes, like triangles, squares, or hexagons, can tessellate because their angles allow for such arrangements.
To be able to tessellate where a vertex meets other vertices, the total of those angles must be a full circle of 360°. The interior angle of an Octagon is 135° which does not divide into 360° which means there cannot be a complete number of vertices meeting and so it cannot, by itself, tessellate. However, two octagons meeting at a point would have 135° + 135° = 270° leaving 90° which is the interior angle of a square. So octagons and squares together will tessellate.
A regular polygon can be drawn using rotations by employing the concept of symmetry around a central point. For example, to create a regular hexagon, one can rotate a line segment around a central point by angles of 60 degrees. This process can be repeated for any regular polygon by rotating a starting line segment by the angle defined by 360 degrees divided by the number of sides of the polygon. Thus, regular polygons such as triangles, squares, pentagons, and hexagons can all be constructed using rotation.
Yes because each interior angle is 120 degrees and angles around a point add up to 360 degrees
Because their angles are factors of 360 and angles around a point add up to 360 degrees
