3.6 Distance from a line (2D/3D geometry). (Section 2.9). A common geometry problem is to determine how far a point S is from a line PQ. The figure to the right shows points P, Q, and S whose position vectors from a point Ao are written in terms of right-handed, orthogonal, unit vectors âx, ây, ây, as FP/Ao = p t Falto = gât F5/40 = szax t syây + száz Denoting C as the point on line PQ closest to S, determine the following (in terms of p, q, 82, Sy, S, and symbols in the table below).
