The statement is not correct.
The sum of the interior angles of an n-sided polygon is (n-2)*180 degrees.
If n is odd, the sum will not be a divisor of 360.
And each individual interior angle will be 180*(n-2)/n degrees. And that will be a divisor of 360 only if n = 3 (triangle), 4 (square) or 6 (hexagon).
And, not by coincidence, these are the only regular polygons that will tessellate a plane surface.
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
Regular polygons are those polygons that are bothequilateral (all sides congruent) and equilateral (all interior angles congruent).

Yes in general polygons that have equal interior angles also have equal sides and they are said to be regular polygons. But a rectangle is an exception.

By definition a regular polygon cannot be concave. Concave polygons contain one or more interior angles that are greater than 180 degrees, and regular polygons can never have an interior degree greater than 180 degrees.
Hexagon.
There is no such regular polygon with 45 degree interior angles; the smallest interior angles in regular polygons are 60 degrees, which is found in a triangle.
Each interior angle of a square is 90 degrees Each interior angle of a regular pentagon is 108 degrees
