Points (1, -1) and (-1, 1) lie in the same quadrant. Is the following statement true or false? Justify your answer

Solution:

The coordinates of points in the quadrants are mentioned below

(+, +) - I quadrant

(-, +) - II quadrant

(-, -) - III quadrant

(+, -) - IV quadrant

The points given are (1, -1) and (-1, 1)

Here (1, -1) lies in the IV quadrant and (-1, 1) lies in the II quadrant

Therefore, the statement is false.
