A regular trapezoid (!) is a square. And each interior angle of a square is 90 degrees.
Each exterior angle of a square is 90 degrees and a square is a regular 4 sided quadrilateral
Each exterior angle of a square measures 90 degrees
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.
