What single transformation is equivalent to a 90 degree counterclockwise rotation followed by a 270 degree counterclockwise rotation?
You went 360o in the same direction, so you end up with a circle.
What is a 90 degree counterclockwise angle equivalent to?
Rotation preserves shape - therefore the angle before the rotation equals the angle after the rotation.
What is the formula for a 90 degree rotation?
A 90 degree rotation is a quarter of a turn.
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 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 a 90 degree counterclockwise angle equivalent to?
Rotation preserves shape - therefore the angle before the rotation equals the angle after the rotation.
How do you find 270 degree clockwise rotation?
(x,y) to (x,-y). You would keep the x the same, but turn the y negative. This is actually the rule for a 90 degree counterclockwise rotation, but they're the same thing, they would go to the same coordinates.

The answer will depend on whether the rotation is clockwise or counterclockwise.
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.
Rule for 90 degrees counterclockwise rotation?
(x,y)-> (-y,x)
Is a 270 clockwise rotation is the same as a 90 counterclockwise rotation?
Both will end up on the same place. Using a compass rose as an example: 270 clockwise will point to the west. 90 counterclockwise will also point west.
What is the image of (1 -6) for a 90 and deg counterclockwise rotation about the origin?
It is (-1, 6).
What is the image of 1 -6 for a 90 counterclockwise rotation about the origin?
(-1, -4) rotated 90 degrees anticlockwise
What is the rule for a 270 degree clockwise rotation?
(x,y) to (x,-y). You would keep the x the same, but turn the y negative. This is actually the rule for a 90 degree counterclockwise rotation, but they're the same thing, they would go to the same coordinates.
