Answer 1. The NCERT solutions for class 11 maths chapter 11 covers the following topics.
1. Introduction
2. Coordinate Axes and Coordinate Planes in Three Dimensional Space
3. Coordinates of a Point in Space
4. Distance between Two Points
Question 2. What Is Three Dimensional Geometry?
Answer 2. Three Dimensional geometry is a branch of maths concerned with the geometry of points, lines, and solid forms in 3D coordinate systems. In 3D geometry class 11, students learn about the Zcoordinate along with the x and ycoordinates, which are used to figure out the exact position of a point within the threedimensional coordinate plane. This basic theory is widely used in other fields of science and in advanced Mathematics. Trigonometric ratios also play an important role in 3D geometry.
