Coordinate geometry is one of the most useful bridges between the realms of diagrams and numbers. As we shall see, it is a two-way bridge; we can solve geometry problems in terms of numbers and also infer certain facts about numerical problems from figures.

1. Cartesian coordinates

(a) Lines and circles

(b) The slope-intersection form

(c) The section formula

(d) The distance formula

(e) Area of a triangle

(f) Graphs of real-valued functions

2. Polar coordinates

(a) Construction of the bijection

(b) Sketching curves
