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.

What happens to the x- and y- coordinates when an object is rotated 90 degrees about the origin?
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
name 2 classification of angle?
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
Which point represents the origin?
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)
What does x-axis mean?
It's the horizontal line on the Cartesian plane that meets the y-axis at the origin at 90 degrees.
What are the coordinates of tha origin?
It's at the point of originwhere the x and y axes intersect at 90 degrees at the coordinates of (0, 0)
