Question 1: Write the answer of each of the following questions:
- What is the name of horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?
- What is the name of each part of the plane formed by these two lines?
- Write the name of the point where these two lines intersect.
Question 2: See Fig.3.14, and write the following:
- The coordinates of B.
- The coordinates of C.
- The point identified by the coordinates (–3,–5).
- The point identified by the coordinates (2, – 4).
- The abscissa of the point D.
- The ordinate of the point H.
- The coordinates of the point L.
- The coordinates of the point M.
Concept: This video tutorial is about what a Coordinate / Cartesian / XY Plane in Coordinate Geometry is. The concept has been explained with detailed examples. It is a recommended video for class 9 students.
Concept: This video tutorial explains that x-coordinate (abscissa) of a point in a cartesian plane is also its perpendicular distance from the y-axis. Similarly y-coordinate (ordinate) of a point is equal to the perpendicular distance of the point from x-axis.
Concept: In this video tutorial, you will learn about the basics of coordinate geometry. This is a must watch video tutorial for class 9 students. This video talks about the coordinate / cartesian plane in length with detailed examples. Different elements of coordinate plane like abscissa and ordinate are also explained with simple examples.
