👉 Quadrangularness is a measure of how many sides a polygon has. A polygon with four sides, for example, is called a quadrilateral. Quadrangularness can be calculated by dividing the total number of sides by 4 and rounding to the nearest whole number. For example, if a polygon has 5 sides, it would have a quadrangularity of 1 (since there are 5/4 = 1 remainder of 1).
