On the JEE Mains and Advanced tests, geometry is one of the most important subjects. Students need to realise that all of the chapters in geometry are related and very important if they want to do well on their standardised tests. By doing problems from the chapter on straight lines, students can make the ideas in later chapters easier to understand. They can also build a strong foundation by doing problems from the chapter. So, it is an important chapter to study for the Mains and Advance papers of the JEE.
