Each of the four interior angles of a square (i.e. a regular quadrilateral) measures 90 degrees
360/4=90
Only if the polygon is a regular quadrilateral.
The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.
90 degrees.
90 degrees
it's 90 degrees
A square has four sides so it is a quadrilateral. All sides of a square are of equal length so it is equilateral. All angles of a square are of equal measure so it is equiangular. A quadrilateral that is equilateral and equiangular is a regular quadrilateral.
It is 90 degrees or pi/2 radians.
If it's a square then it's 90 degrees
