You could rotate it in either direction, like a steering wheel.
-- If you rotate the whole plane 90 degrees to the left, then the old x-coordinate
of every point becomes its new y-coordinate, and its old y-coordinate becomes its
negative x-coordinate.
-- If you rotate the whole plane 90 degrees to the right, then the old x-coordinate
of every point becomes its new negative y-coordinate, and its old y-coordinate
becomes its new x-coordinate.

The answer depends on whether the rotation is clockwise or anti-clockwise.For anti-clockwise rotation (the standard direction of rotation),old x-coordinate becomes new y-coordinate,old y-coordinate becomes minus new x-coordinate
The 4 classifications are:- 1 Acute angle which is greater than 0 but less than 90 degrees 2 Right angle which is 90 degrees 3 Obtuse angle which is greater than 90 but less than 180 degrees 4 Reflex angle which is greater than 180 but less than 360 degrees A full rotation is 360 degrees
On the Cartesian plane the x and y axes are perpendicular to each other and they meet at 90 degrees at the point of origin which have coordinates of (0, 0)
It's the horizontal line on the Cartesian plane that meets the y-axis at the origin at 90 degrees.
It's at the point of originwhere the x and y axes intersect at 90 degrees at the coordinates of (0, 0)
