A square.
Square, or a rectangle. * * * * * Since it is a REGULAR polygon, it cannot be a rectangle. So the only answer is a square.
Right angle not polygon. (i'm not mad).
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.
4. All exterior angles add up to 360 on a polygon, regardless of the amount of sides.

wrong- that's only a right angle
Right angle not polygon. (i'm not mad).
The sum of the exterior angles of a polygon is 360 degrees. If it is a regular polygon, then it has 360/4 = 90 vertices and so 90 sides.
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.
If each angle measures 90 degrees the polygon is a square and so its angles sum to 360 degrees.
Any regular polygon with more than 4 sides has angles of more than 90 degrees. Some examples would be:PentagonHeptagonOctagonNonagonDecagonDodecagon
If it is a regular polygon and each interior angle is 176 degrees then it will have 90 sides.
4. All exterior angles add up to 360 on a polygon, regardless of the amount of sides.
The name of a 90 sided polygon is Enneacontagon
