W.08 Law III: The Spread Law & Extended Circumquadrance Law
In any non-null triangle A_1 A_2 A_3 with side quadrances Q_1, Q_2, Q_3, vertex spreads s_1, s_2, s_3, quadrea A, and circumquadrance K, the ratios of spread to opposite quadrance are equal: s_1 / Q_1 = s_2 / Q_2 = s_3 / Q_3 = A / (4 * Q_1 * Q_2 * Q_3) = 1 / (4 * K).
