S M Nazmuz Sakib Cosine–Weighted Pedal Isometry: A Tight-Frame Identity for Triangle Side Normals

open access: yes
We present a new quadratic identity in Euclidean triangle geometry—the S M Naz-muz Sakib Cosine–Weighted Pedal Isometry. Given a nondegenerate triangle ABC witharea ∆ and circumradius R, and signed perpendicular distances da(X), db(X), dc(X)from any point X to the sidelines BC, CA, AB, respectively, define weights wa = a cos A(cyclically). Then for all
