Bihar Board Class 9th Maths Solutions Chapter 3 Coordinate Geometry Ex 3.2 Textbook Questions and Answers.

## BSEB Bihar Board Class 9th Maths Solutions Chapter 3 Coordinate Geometry Ex 3.2

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.

Solution:

- The name of horizontal and vertical lines drawn to divide the plane into four parts is rectangular axes/coordinate axes.
- The name of each part of the plane divided by axes is quadrant.
- The axes intersects at the origin.

Question 2.

See figure, 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 point L.
- The coordinates of the point M.

Solution:

Clearly, from the figure :

- The coordinates of B are (- 5, 2).
- The coordinates of C are (5, – 5).
- The coordinates (- 3, – 5) are identified by the point E
- The coordinates (2, – 4) are identified by the point G
- The abscissa of the point D is 6.
- The ordinate of the point H is – 3.
- The coordinates of the point L are (0, 5)
- The coordinates of the point M are (- 3, 0).
