There are many ways of describing the rule. Perhaps the simplest is to premultiply the coordinates of any point by the matrix:( 0 -1 )
( 1 0 )
{1 0} {0 -1}
(-1, -4) rotated 90 degrees anticlockwise
Rotating a triangle 90 degrees counterclockwise would involve taking an upright triangle and laying is toward the left on its back. Changing position through rotation can cause a better visualization for some problem solving.

It is an anticlockwise rotation through 90 degrees.
(x,y)-> (-y,x)
Clockwise means turning to your right, counterclockwise is to the left.
A counterclockwise rotation of 270 degrees about the origin is equivalent to a clockwise rotation of 90 degrees. To apply this transformation to a point (x, y), you can use the rule: (x, y) transforms to (y, -x). This means that the x-coordinate becomes the y-coordinate, and the y-coordinate becomes the negative of the x-coordinate.
Yes, a 270-degree clockwise rotation is the same as a 90-degree counterclockwise rotation. When you rotate an object 270 degrees clockwise, you effectively move it 90 degrees in the opposite direction, which is counterclockwise. Both rotations will result in the same final orientation of the object.

The answer will depend on whether the rotation is clockwise or counterclockwise.

Uranus is the only planet tilted 90 degrees to the right
An equivalent transformation to rotating a figure 90 degrees counterclockwise can be achieved by reflecting the figure across the line (y = x) and then reflecting it across the x-axis. This combination of reflections results in the same final orientation as the 90-degree counterclockwise rotation.
The answer will depend on whether the rotation is clockwise or counterclockwise.
