Cartesian coordinate geometry is a very important topic that analyzes measurements of distances, calculations of points and angles on a Cartesian plane. A student willing to acquire great skills on this topic has to master the formulas in each section and properly understand the concept. This has been handled properly in the course of these lessons and everything needed to become a master in this course has been properly treated. A good knowledge of Cartesian coordinate geometry is very important at the ordinary level, the advanced level and even in the university as geometry is part of our everyday lives.
