Question

A point lies in quadrant II. After a rotation of negative 90°, the point will lie in quadrant _____.

I
II
III
IV

Answer 1

A point lying in Quadrant II will undergo a rotation of -90°, which corresponds to a clockwise rotation. After this rotation, the point will end up in Quadrant I. (option A)

A point in Quadrant II of the Cartesian coordinate system has positive x-coordinates and negative y-coordinates. Performing a rotation of -90° involves a clockwise rotation. In Quadrant I, both x and y coordinates are positive.

As a result, the point initially in Quadrant II, with its positive x-coordinate and negative y-coordinate, will rotate clockwise and end up in Quadrant I, where both coordinates are positive. Thus, the final position of the point, following a rotation of -90°, will be in Quadrant I, with positive values for both x and y coordinates. (option A)

Answer 2

Use this picture to define. It will be III quadrant.
