Hi Aspirant!

Co-ordinate geometry is considered one of the most important sections of the mathematics. It describes the link between algebra and geometry through graphs which involves curves and lines.

I am considering  your query in the context of 11th and 12th class.

Chapters considered under co-ordinate geometry are:

• Introduction to 3D-Geometry - 11th class NCERT (Chapter 12)
• Three Dimensional Geometry - 12th class NCERT (Chapter 11)

Kindly note that to understand the basics of 3D geometry one should learn the complete basics of 2D geometry first.

Thankyou!
