Projective Geometry is a branch of mathematics that studies the properties of figures that remain invariant under projection. Unlike traditional geometry, which focuses on distances and angles, projective geometry emphasizes the relationships between points, lines, and planes. It introduces concepts like points at infinity, where parallel lines meet, allowing for a more comprehensive understanding of geometric properties. In projective geometry, the fundamental elements are points and lines, and the focus is on their intersections and configurations. This field has applications in various areas, including computer graphics, art, and perspective drawing, where it helps create realistic representations of three-dimensional objects on two-dimensional surfaces.
