The answer is the 3rd one
Answer: A. A tessellation that uses only one type of regular polygon
Step-by-step explanation:
When we cover a surface with a pattern of a flat geometric shapes such that there should have no overlaps or gaps, then the surface is called a tessellation.
A regular tessellation is tessellation made up by using nly one type of regular polygon. These are made up of entirely congruent regular polygons all that joining vertex to vertex
Hence, A is the correct option.
A.0.8 < 5/6 < 12/13
because 5/6 = .83 and 12/13 = .92
