# NCERT Solutions Class 11 Maths Chapter 12 Exercise 12.2 Introduction to Three Dimensional Geometry

NCERT Solutions for Class 11 maths Chapter 12 exercise 12.2 Introduction To Three Dimensional Geometry helps us to further navigate our way through the three-dimensional space. In these exercises, the students will get practice and understanding of how the location of a point expressed in three coordinates can be used to find various different information. The NCERT solutions Class 11 maths Chapter 12 exercise 12.2 has five questions, out of which 2 questions require short answers while the remaining 3 questions need explanation.

This exercise requires the students to find the distance between two points, or distance of a point from a line, and also to deduce whether the three coordinates of given points would be in a straight line or not. Kids will further see the angle made by two lines, the points of which are expressed using x, y, and z coordinates. As we can deduce the length and angle made between lines, some questions go further ahead to identify the kind of triangle the lines would make.

## NCERT Solutions Class 11 Maths Chapter 12 Exercise 12.2 Tips

NCERT solutions Class 11 maths Chapter 12 exercise 12.2 Introduction To Three Dimensional Geometry requires the ability to see a point in the three-dimensional space. The point in space that can be accurately represented by three coordinates is an idea using which the whole universe can be mapped. The students must take note that the coordinates of a point P, in the three-dimensional geometry, are represented in the form of (x, y, z), where x, y, and z are the measures from the YZ, ZX, and XY-planes.

NCERT solutions Class 11 maths Chapter 12 exercise 12.2 highlights the practical utility of the three coordinates, and how using these, the basic calculations such as distance of a point and angle between the lines can be found out. These concepts lay the building block for understanding shapes like triangles and parallelograms.
