More Golden Quadrilaterals, This Time Based on Sides

By Jim Fonseca

Figure 1: A Golden Lateral Quadrilateral with Side of 1 Opposite 4.236 (Perimeter = 9.472; sum of angles = 360.000)

My previous posts on Medium introduced a new type of Golden Triangle based on its three angles in the proportion of the Golden Ratio. Then I showed how the same approach could be used to define Golden Quadrilaterals with their four angles in proportion to the Golden Ratio: 160.997°, 99.502°, 61.495° and 38.006°.
