algebraic projective geometry | descriptive geometry | geometry of position | higher geometry

The branch of geometry dealing with the properties and invariants of geometric figures under projection. In older literature, projective geometry is sometimes called "higher geometry, " "geometry of position, " or "descriptive geometry" (Cremona 1960, pp. v-vi).
