These three mutually perpendicular lines form three planes namely XY, YZ, ZX called coordinate planes. All you need of JEE at this link: JEE SHORT ANSWERS TYPE QUESTIONS Q.1. Introduction to Three Dimensional Geometry Practice Questions Determine the direction cosines of a line L if it makes angles 135°, 90°, and 45° with x, y, z-axes. Section Formula Introduction to 3-D Geometry An octant is one of the eight divisions of a Euclidean three-dimensional coordinate system. Any point that lies on the X-axis will have its coordinates in the form (x, 0, 0). To locate position of an object in a line, you just need the distance of the object from the point of reference. Notes Introduction to Three Dimensional Geometry OPTIONAL - I Vectors and three dimensional Geometry 33 INTRODUCTION TO THREE DIMENSIONAL GEOMETRY You have read in your earlier lessons that given a point in a plane, it is possible to find two numbers, called its co-ordinates in the plane. In three-dimensional space, we identify a point with respect to the distances from the three reference planes. Book a Free Class. Three mutually perpendicular lines intersect at one point, the point O(0, 0, 0) is known as the origin in the space. Download this solution for FREE Download this PDF, © Copyright Vidyakul.
