the answer is true -apex
No. Regular tessellations use only one polygon. And, according to the strict definition of regular tessellation, the polygon must be regular. Then a tessellation using rectangles, for example, cannot be called regular.
Tessellations of regular polygons can occur only when the external angle of a polygon is equal to a factor of 360. As such, the only tessellations of regular polygons can occur when the internal angles of a polygon are equal to a factor of 360. As such, the only regular polygons which tessellate are triangles, squares, and hexagons.
Sometimes. By definition, a semi-regular tessellation must include more than one type of regular polygon. Some uniform tessellations use more than one type of regular polygon, but many uniform tessellations use only a single regular polygon. Therefore the statement is only sometimes true.
False
Yes, there are only 8.
it seems to me that the only polygon of your description is a square
Only when it has 3 or more equal sides then it is a regular polygon
Only if the polygon is a regular quadrilateral.
Regular * * * * * Equilateral. It is regular only if all its angles are also congruent. A rhombus is NOT a regular polygon, a square is the only regular quadrilateral.
No. Squares and regular hexagons, both with an even number of sides, can make regular tessellations.
No. Squares and regular hexagons, both with an even number of sides, can make regular tessellations.
Only when the polygon is a regular convex polygon. Such as an equilateral triangle, or a square, or a regular pentagon.
