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)
(-1, -4) rotated 90 degrees anticlockwise
90 degrees
90 degrees is a 1/4 of a full rotation of 360 degrees
No, degrees are not a measure of area, but of rotation.
90
A turn through 90 degrees.
1/4 of 360 degrees = 90 degrees which is a right angle
The answer will depend on whether the rotation is clockwise or counterclockwise.
It is 1/4 of a turn
If its 2d, you need a point of rotation If its 3d, you need an axis of rotation
The answer will depend on whether the rotation is clockwise or counterclockwise.
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.
