Q2 of 26 Page 93

In which quadrant are the following points?

i. whose both co-ordinates are positive.


ii. whose both co-ordinates are negative.


iii. whose x co-ordinate is positive, and the y co-ordinate is negative.


iv. whose x co-ordinate is negative and y co-ordinate is positive.

According to co-ordinates Geometry,

i. In First Quadrant, both co-ordinates are positive.


ii.In Third Quadrant, both co-ordinates are negative.


iii.In Fourth Quadrant, x co-ordinate is positive and the y co-ordinate is negative.


iv.In second Quadrant, x co-ordinate is negative and y co-ordinate is positive.
