Regular Hexagon, Square, and Equilateral Triangle. (Apex)
An octagon can be used to create a tessellation, but an octagon cannot tessellate on its own.
From what I have been able to find out (using my daughter's homework) is that "Power Polygons" are any "normal" polygon that can be combined with another "normal" polygon to form another, different looking polygon (a mega-polygon, I guess?)that you can then divide up so you can see the individual "Power Polygon" pieces. Perhaps the name "Power Polygons" is derived from the fact that these polygons have the power to create other polygons. Logically then a "Power Polygon" is, really, just any polygon, just with a new, exciting, and high tech sounding name.
No it is not.

Most regular polygons will not - by themselves. In fact, of the regular polygons, only a triangle, square and hexagon will. No other regular polygon will create a regular tessellation.

Assuming that the question refers to a regular octagon (not a regualr otagon), the answer is no.
Most regular polygons will not - by themselves. In fact, of the regular polygons, only a triangle, square and hexagon will. No other regular polygon will create a regular tessellation. However, for polygons with any number of sides, there are irregular versions that can tessellate.
No - because they would leave a small, square-shaped space between each tile.
