(x,y)-> (-y,x)
180 degrees.
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
A rotation of 270 degrees counterclockwise is a transformation that turns a figure around a fixed point by 270 degrees in the counterclockwise direction. This rotation can be visualized as a quarter turn in the counterclockwise direction. It is equivalent to rotating the figure three-fourths of a full revolution counterclockwise.

(x,y)-> (-y,x)
180 degrees.
{1 0} {0 -1}
(-1, -4) rotated 90 degrees anticlockwise
The answer will depend on whether the rotation is clockwise or counterclockwise.
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.
Something that is tilted 90 degrees has been rotated a quarter turn clockwise or counterclockwise from its original orientation. This means it is now perpendicular to its original position.
The answer will depend on whether the rotation is clockwise or counterclockwise.
A) Rotate 360 degrees counterclockwise, then shift 1 unit up. B) Rotate 180 degrees counterclockwise, then shift 1 unit down. C)Rotate 90 degrees counterclockwise, then shift 1 unit up. D) Rotate 270 degrees counterclockwise, then shift 1 unit down.
1/4 of 360 degrees = 90 degrees which is a right angle
"East" is a directional term that refers to the direction you would face when observing the sun rise. It can also be found by rotating 90 degrees clockwise from north, or by rotating 90 degrees counterclockwise from south.
Assume we want to find the ordered pair after 90° counterclockwise rotation. From (x,y), we have (-y,x). If we want to find the ordered pair after 90° clockwise rotation, then from (x,y) we have (y, -x)
