This decagonal mandala is split into fifty golden triangles (shown in yellow), and forty golden gnomons (shown in orange).
In this tessellation, golden rectangles are shown in yellow. The orange darts are each made of two golden gnomons, joined at a leg — while the blue rhombi are each made of two golden triangles, sharing a base.
