Answer:
option A) yes, measure of interior angle is 90
Explanation:
Tessellation:
the tiling of an flat surface or plane by one or more geometric surfaces is tessellation. No overlapping or gap or un-evenness is left during tessellation, all the shapes fit perfect to the plane or flat surface. There are three geometric shapes that can be used for tessellation.
These shapes are:
Square
Triangle
Hexagon
As in given problem the polygon given is square
So YES the tessellation of plan is possible and the as the interior angle of square is 90 degrees so
option A is correct complete answer i.e. yes, measure of interior angle is 90 !
