Rule for 90 degrees counterclockwise rotation?
(x,y)-> (-y,x)
Why doesn't the direction of rotation clockwise and counterclockwise matter when the angle of rotation is 180?
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
How many degrees right angle?
90 degrees 90 degrees
How many degrees has triangle ABC been rotated counterclockwise about the origin?
180 degrees.
What is the complement of 83.5 degrees?
It is: 90-83.5 = 6.5 degrees
Rule for 90 degrees counterclockwise rotation?
(x,y)-> (-y,x)
How do you rotate a polygon 90 degrees counterclockwise about the origin?
{1 0} {0 -1}
What is the image of 1 -6 for a 90 counterclockwise rotation about the origin?
(-1, -4) rotated 90 degrees anticlockwise
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.
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.
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.
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.
What is one fourth of a rotation going counterclockwise?
1/4 of 360 degrees = 90 degrees which is a right angle
What is the definition for east?
"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.
How do you get an ordered pair of 90 degrees?
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)
What is the rule for a 90 degrees counterclockwise?
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 )
Why doesn't the direction of rotation clockwise and counterclockwise matter when the angle of rotation is 180?
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
