Euclid is popularly referred to as the Father of Geometry. He was a Greek mathematician. He applied elements in the geometry field to depict the work in two frames. He made contributions to the optics and conics field. That's why he is sometimes referred to as founder of optics also.
Coordinate geometry (or analytical geometry) allows the algebraic representation of geometric shapes. This then allows algebraic concepts to be applied to geometry.
When you study the theory of geometry, it is pure mathematics. However, when you start using the geometry you have learned in other, more practical areas, then it becomes applied.
