Triangular Equilibrium

Two glossy playing cards rested flat on the polished dining table. I retrieved both, propping their top edges together to form an inverted triangle. The slick coated paper offered minimal surface traction. Immediate lateral drift threatened the apex. Anchoring my left foot, I stabilized the diagonal flank with my fingertip while nudging the opposing base outward by two millimeters. The angle locked at sixty degrees. Zero lateral wobble. With measured bilateral control, I lifted a third card from the deck and laid it horizontally across the twin peaks. The bridge held firm without displacement. Framework established. Balance confirmed.
