29.5.5 Solving Combined Solid Geometry Problems with Vectors
Core ideaParallelism, perpendicularity, angles, and distances all bundle into one problem, solved in a single stroke by coordinates and dot products.
Module goal. Use the idea of projection to find the distance from a point to a plane, pull together the full routine of setting up axes, assigning coordinates, and finding vectors, and pave the way for the next stage where analytic geometry makes geometry fully algebraic.
