Perp-2D-Strips-Equal-Width — Perpendicular Surfaces

Geometry Class: Perpendicular Surfaces
Geometry Id: Perp 2D Strips Equal Width
Configuration Notes: 2D Case of Inclined Equal-Width Strips at ALPHA=90 Deg Sharing Common edge. by Hottel Crossed-String Method for Equal-Width Perpendicular strips: F12=1-SIN(45)=0.2929. F21=F12 by Reciprocity and Symmetry (equal areas).
Formula Expression: F12=1-SIN(ALPHA/2) with ALPHA=90 deg; = 1-SQRT(2)/2 ≈ 0.2929
