We explain geometrically why ordinary facet angles of a stroked path tessellated from uniform tangent angle steps are bounded by twice the step angle. This fact means—excluding a small number of extraordinary facet angles straddling offset cusps—our polar stroking method bounds the facet angle size to less than 2 θ where θ is the tangent step angle.
