All you need for 3D Geometry Class 12th
So finally you’re able to make it to the third last chapter of your class 12th math syllabus. Horrayy! But this shit is a little confusing, yes right, 3D geometry. Or simply, we don’t know xD. The chapter is the centralist player, just playing around with us. ENOUGH! JUST ENOUGH!
Bro, All I see now is Shapes everywhere around me from a different perspective.
Chapter revolves around a few topics like,
● Important Notes
● Line Equations
● Plane Equations
● Conclusion
Three-dimensional space (also: 3D space, 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point). This is the informal meaning of the term dimension.

Finding a point’s precise placement in a 3D space requires the input of three parameters. Due to the large number of questions in the JEE tests, 3-D geometry is a crucial subject. In this post, we’ll look at some fundamental ideas in 3-dimensional coordinate geometry that will help us grasp how to perform various operations on points in a 3-dimensional plane.
Well enough of this, let’s come down to the down point. The chapter is a bit confusing and tricky. And just after doing so much into calculus, you must not be thinking this way for sure, cause probability requires a bit of thinking the round way. So here’s the reason why we’re here! Bit of tips and tricks will make your way into it.
Tips & Tricks
- Don’t Mess up
The one and only thing with 3D geo is that you read it after Calculus, so much of theory and then different sets of questions. See you need to have a different approach for this chapter, as it deals with calculations and deep thinking skills.
- Cover the basics
Yes, Cover the basics, as there can be n number of questions from this chapter and all require a good concept. And even if something irrelevant occurs, that you have never came across, you’ll be able to solve that by hook or crook.
- PRACTICE, PRACTICE, PRACTICE
Probability, yes, you don’t know which thing can come in your favor. As, this question might come or that, you never know. So just to ensure, practice, as much as you can.
Important Notes
The chapter on 3D geometry and vectors uses formulas. Due to the abundance of formulas and mathematical concepts, a learner can find this challenging. Students can readily comprehend the concepts in this chapter once they have a basic understanding of how the formulas were created. This chapter contains both short and long formulas. For the CBSE boards, JEE 2022, and other olympiad exams 2021–2022, these are all prerequisites. This chapter has long answer questions, thus students should be well-versed in all the concepts and formulas. To speed up the final test, each question in the NCERT Solutions for Class 12 must be solved twice. For solutions to the issues, a student must ask their teachers or consult the NCERT solutions for 3D geometry. They can also search for and solve problems in question papers from prior years to get a better grade.
