Best Answer

A rectangle (each internal angle must also be 90 degress). It is a 4-sided shape as 360/90 = 4.

Another contributor's answer:

If it's a regular polygon then all sides must be equal. A square has 4 equal sides and 4 exterior 90 degree angles.

Q: If the exterior angle of a regular polygon equals 90 degrees what is the pylygon?

A regular polygon with exterior angles of 30 degrees has: 360/30 = 12 sides

That's true if the interior angles are 108 degrees, but a regular polygon cannot have exterior angles of 108 degrees.

No.

The sum of all exterior angles of a polygon is 360 degrees. In a regular polygon, all of the exterior angle are equal, so there must be 360/72=5 sides of the polygon, which makes it a pentagon.

A regular polygon will have 360 sides with exterior angles of 181 degrees.

There can be no such polygon. The sum of the exterior angles of ANY polygon is 360 degrees. If it is a regular polygon, then the number of angles MUST divide 360 degrees. Since 18.95 does not divide 360, there cannot be such a polygon. If the exterior angle was 18.94737... degrees, it would be a 19-sided polygon.

If its a regular 9 sided polygon then the exterior angles are 40 degrees.

Each exterior angle is 15 degrees
