The tessellating polygons must meet at a point. At that point, the sum of the interior angles of the polygons must 360 degrees - the sum of angles around any point. Therefore, each interior angle must divide 360 evenly. There is no 1 or 2 sided polygon. The interior angle of a regular pentagon is 108 degrees which does not divide 360 degrees. The interior angles of regular polygons with 7 or more sides lie in the range (120, 180) degrees and so cannot divide 360.
That leaves regular polygons with 3, 4 or 6 sides.
Equilateral triangles, squares, and hexagons.
Mostly true - you cannot tessellate only regular pentagons in two dimensions, since you cannot sum up the intersection of the angles to 360 degrees. If you tessellate a regular pentagon in three dimensions, you end up with a dodecahedron.
In a normal plane, only regular polygons with interior angles that are a factor of 360o can be tessellated. This means only three shapes: the regular (equilateral) triangle, the regular quadrilateral (square) and the regular hexagon. If the line were considered a regular polygon (with only two sides) then it would also be included in this list.
True...
A polygon is a two dimentional (or plane) geometrical figure that has three or more sides to it. If all the sides are of the same length, then it is known as a regular polygon.
Equilateral triangles, squares, and hexagons.
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.
No only three can tesselate. they are: An equilateral triangle, a square and a 6 sided hexagon.

There are only three regular polygons which can make a regular tessellation?

True Apex
No. The interior angle of a regular pentagon is 108 degrees, the interior angle of a regular hexagon is 120 degrees. So, at the vertex, the three polygons will have angles adding up to 108+120+120 = 348 degrees. To tessellate, or cover the surface, they must add to 360 degrees.
Tessellated image can be one of two things 1 a repeating pattern, wether it be a bunch of blue squares or more complex shapes Or 2 what happens when a grid is displayed on a screen too low resolution to display it (happens all the time on my 1080p monitor) it's like if you look at a brick wall then woomera out on the pc, those lines that appear are tesselations
