Introduction To refer to a point in space we require a third axis (say z-axis) which leads to the concept of three-dimensional geometry. QnA , Notes & Videos The coordinates of points on the x axis are of the type (x,0,0), on the y axis are (0,y,0) and on the z axis are (0,0,z) you agree to One of the bases for advanced mathematics, it is a chapter that is not just important for Class 11, but also if you plan to study maths or physics in … OTP, Terms and 2 hours 0 mins . If we draw three planes intersecting at O such that they are mutually perpendicular to each other, then these will intersect along the lines X′OX, Y′OY and Z′OZ. Three mutually perpendicular lines intersect at one point, the point O(0, 0, 0) is known as the origin in the space.

The aim is to present standard properties of lines and planes, with minimum use of complicated three–dimensional diagrams such as those involving similar triangles. It has 6 faces, 8 vertices, and 12 edges; Cylinder. The coordinate axes divide the coordinate space into parts, called octants. Scalar and Vector Products Assignment web page ! These three mutually perpendicular lines form three planes namely XY, YZ, ZX called coordinate planes. These lines are called the coordinate axes and the two numbers are called the coordinates of the point with respect to the axes.
