Projective geometry is closely related to perspective geometry. These types of geometry originated with artists around the 14th century.
Projective Geometry is the study of the descriptive properties of geometric figures. It deals with objects/shapes that have been distorted/skewed by perspective transformations.
The Projective Plane:
1.) Homogeneous coordinates
2.) The Principle of Duality
3.) Pencil of lines
4.) Cross Ratio
6.) Absolute Point
8.) Laguerre formula
