NCERT solutions for class 11 maths chapter 11 exercise 11.2 Introduction to three dimensional geometry, the students need to figure out the distance between two points, or the distance of a point from a line, and they also need to figure out if the three coordinates of the given points would be straight or not. In addition, students will observe the angle formed by two lines whose points are represented using the x, y and z coordinate. While the length and the angle formed between the lines can be determined. Some questions further are to determine the type of triangle that the lines would form.
Ex 11.2 class 11 maths chapter 11 NCERT solutions consist of 5 questions, out of which two questions are short answer type while three questions require explanation. This exercise is about solving problems using an equation. To understand how to solve these problems, you need to understand the equation. Class 11 maths chapter 11 exercise 11.2 NCERT solutions are developed by eSaral’s subject experts who have explained the concepts and equations to score good marks in exams.

Topics Covered in Exercise 11.2 Class 11 Mathematics Questions
Ex 11.2 class 11 maths chapter 11 Introduction to three dimensional geometry is totally based on distance between two points and also you will learn an equation related to this topic.
Distance between Two Points
Distance between Two Points
Let’s suppose we have two points (x1, y1, z1) and (x2, y2, z2) in three dimensional space. The formula for determining the distances between two points in three-dimensional space is analogous to Euclid's formula for the distances studied in two-dimensional space. This formula is a minor alteration to Euclid's original formula.
Distance between two points P(x1 , y1 , z1 ) and Q (x2 , y2 , z2 ) is given by
Tips for Solving Exercise 11.2 Class 11 Chapter 11 Introduction to Three Dimensional Geometry
NCERT solutions class 11 maths chapter 11 exercise 11.2 Introducing to three dimensions geometry necessitates the capacity to visualize a point in a three-dimensional space. Students need to follow useful tips to solve exercise questions which are provided by subject experts of eSaral.
Students need to understand that in 3D geometry, a point P is represented as x, y, z where x, y and z being the measures from YZ, ZX, and XY planes respectively.
