The formula is (x,y) -> (y,-x).
Verbal : switch the coordinates ; then change the sign of the new x coordinate.
Example : (2,1) -> (1,-2)

How do you rotate a polygon 90 degrees counterclockwise about the origin?
{1 0} {0 -1}
How do you rotate a triangle 90 degrees 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.
How do you rotate a figure 90 degrees counterclockwise about origin?
Ex: -1,-2 Switch the numbers, so with the example it would be -2,-1. Next multiply your x coordinate by -1,so the example would be 2,-1
What is the image of 1 -6 for a 90 counterclockwise rotation about the origin?
(-1, -4) rotated 90 degrees anticlockwise
How do you rotate a figure 90 degrees counter clockwise about the origin?
You have to switch the x and y coordinates and multiply your new x coordinate by -1. You can also dram the point and rotate your paper physically by 90 degrees. Example: Your Coordinates: (3,8) New Coordinates: (-8,3) (3,8) ---> (8,3) ---> (-8,3) Another Ex: (-7,-1) --> (-1,-7) --> (1,-7)
Suppose a figure is located in quadrant 1. Which of the following will result in an image that is located in quadrant 3?
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.
How do you rotate a polygon 90 degrees counterclockwise about the origin?
{1 0} {0 -1}
Rotate do you rotate a figure 270 degrees counterclockwise?
270 degrees is 3/4 of the way around the circle. Ir is the same as rotating it 90 degrees (1/4) of the way clockwise. Turn it so anything that was pointing straight up would be pointing to the right.
How do you rotate a figure 270 degrees clockwise about origin?
You dont, its just 90 degrees 3 times..
How do you rotate a triangle by 90 degrees clockwise?
rotate it 90 degrees
How do you rotate a triangle 90 degrees 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.
How do you rotate a figure 270 degrees?
Rotating a figure 270 degrees is like rotating the figure to the left 90 degrees. I am not sure what formula or rule you use. *Joe Jonas Rocks*
How do you rotate a figure 90 degrees anticlockwise?
Clockwise is rotating something to the right, anticlockwise is moving something to the left. It is basically the same thing as counterclockwise. The prefix ANTI- means "not." Examples: Antisocial, antichrist, antimatter, and so on.
How do you rotate a figure 90 degrees counterclockwise about origin?
Ex: -1,-2 Switch the numbers, so with the example it would be -2,-1. Next multiply your x coordinate by -1,so the example would be 2,-1
How do you rotate a figure 90 degrees?
the answer would be 180 degrease and if you don't believe me go on another website...
Will the sides of the triangle change if rotate a figure 90 degrees clockwise about origin?
No, only their positions will change.
What is 90 degrees counterclockwise?
Clockwise means turning to your right, counterclockwise is to the left.
