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)
What is the image of 1 -6 for a 90 counterclockwise rotation about the origin?
(-1, -4) rotated 90 degrees anticlockwise
How many degree is two times a quarter of a rotation?
90 degrees
What fraction of a full rotained is 90?
90 degrees is a 1/4 of a full rotation of 360 degrees
Can the area be 180 degrees and the perimeter be 90 degrees?
No, degrees are not a measure of area, but of rotation.
How many degrees in a quarter rotation?
90
What is a quarter rotation?
A turn through 90 degrees.
What is one fourth of a rotation going counterclockwise?
1/4 of 360 degrees = 90 degrees which is a right angle
What is the image of the point (43) if the rotation is 90 degrees?
The answer will depend on whether the rotation is clockwise or counterclockwise.
90 degrees clockwise rotation?
It is 1/4 of a turn
What is the image of point (-1-2) if the rotation is 90 degrees?
The answer will depend on whether the rotation is clockwise or counterclockwise.
How do you rotate an object 90 degrees?
If its 2d, you need a point of rotation If its 3d, you need an axis of rotation
A reflection in the line y equals x followed by a rotation of 90 degrees about the origin is equivalent to what single transformation?
For a rotation, other than of 180 degrees, it is necessary to specify whether it is clockwise or anticlockwise. Since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
