👉 In mathematics, a projective space is an example of a geometric space that can be defined in terms of lines and planes. A plane is one such space where every line meets at exactly one point, while each line intersects every plane in precisely two points. This property is known as the "projective" property of a plane. A projective space is constructed by considering all possible positions for a line (or plane) within the space, and then associating these positions with lines or planes that
