Previous knowledge of 3-D Geometry

In Class XI, as we study analytical geometry in two dimensions and introduce three-dimensional geometry, we limit ourselves to Cartesian methods only. In class 12 Maths chapter 10, we have learned about some basic concepts of vectors. Now we will use vector algebra for three-dimensional geometry. The purpose of this approach to three-dimensional geometry is that it makes the study simple and elegant.

Three dimensional geometry in mathematics from class 12

In Mathematics Class 12, Chapter 11, we will study about the fundamentals of 3-D geometry like the direction cosine and direction relationship of a line joining two points and we will also discuss equations of lines and planes in different situations, the angle between two lines, two planes. , A line and a plane, the shortest distance between two oblique lines and the distance of a plane from a point. Most of the above results are obtained in vector form. However, we will also translate these results into Cartesian form, which sometimes presents a clear geometric and analytical picture of the situation.

Equation of a Line in Space

We have gone through the equation of lines in two dimensions in eleventh grade, now we will study vector and Cartesian equations of a line in space. A line is uniquely determined if (i) passes through a given point and is its given direction, or (ii) passes through two given points.
