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.


What is the rule for a counterclockwise rotation about the origin of 270?

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.


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.


What is one fourth of a rotation going counterclockwise?

1/4 of 360 degrees = 90 degrees which is a right angle


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 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 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 a rotation of 270 Degrees clockwise?

A rotation of 270 degrees clockwise is equivalent to a rotation of 90 degrees counterclockwise. In a Cartesian coordinate system, this means that a point originally at (x, y) will move to (y, -x) after the rotation. Essentially, it shifts the point three-quarters of the way around the origin in the clockwise direction.


What is 90 degrees counterclockwise?

Clockwise means turning to your right, counterclockwise is to the left.


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 )


What transformation is represented by the rule (x y) (y -x)?

It is an anticlockwise rotation through 90 degrees.


How do a 90 counterclockwise look like?

A 90-degree counterclockwise rotation involves turning an object or point 90 degrees to the left around a specified pivot point. For example, if you imagine a point on a Cartesian coordinate system, moving it 90 degrees counterclockwise would shift its position from, say, (1, 0) to (0, 1). This transformation effectively swaps the x and y coordinates and changes the sign of the new x-coordinate.
