## FAQs on Three Dimensional Geometry Class 12 Notes CBSE Maths Chapter 11 [Free PDF Download]

1. What is the Central Idea of 3D and Axes?

Space has an infinite number of points. To identify each and every point of space with the help of three perpendicular coordinate axes AB, AC and AD is what central idea of 3D is all about. While revising from Class 12 Maths Revision Notes Solution Chapter 11 students will get to know more about it. Axes are referred to as three mutually perpendicular line AB, AC, AD.

2. What are ‘Coordinates of a Point?’

As explained in Three-dimensional Geometry Class 12 Notes, coordinates of a point are a set of numbers that denote the point’s exact location in a two-dimensional plane or three-dimensional space. In a 2D plane, for instance, there are two axes- X and Y, and the coordinates are nothing but the distance of the point from each axis.
