we swap the co-ordinates and give the new y co-ordinate the opposite sign.
90 degrees clockwise(y, -x)
The effect of the rotation is the same as that of a 90 degree clockwise rotation. In matrix notation, it is equivalent to [post-]multiplication by the 2x2 matrix: { 0 1 } {-1 0 }
The answer will depend on whether the rotation is clockwise or anti-clockwise.
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.
A transformation, in the form of a rotation requires the centre of rotation to be defined. There is no centre of rotation given.
90 degree anticlockwise.

Yes, a 270-degree clockwise rotation is the same as a 90-degree counterclockwise rotation. When you rotate an object 270 degrees clockwise, you effectively move it 90 degrees in the opposite direction, which is counterclockwise. Both rotations will result in the same final orientation of the object.
plz awnser this
(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.

To rotate a figure 90 degrees clockwise around the origin on a coordinate grid, you can use the transformation rule: (x, y) becomes (y, -x). For the point (5, 5), applying this rule results in (5, -5). Therefore, after a 90-degree clockwise rotation, the new coordinates of the point are (5, -5).
To find the image of the point (4, 3) after a -90-degree rotation (which is equivalent to a 90-degree clockwise rotation), you can use the rotation formula: (x', y') = (y, -x). Applying this to the point (4, 3), the new coordinates become (3, -4). Therefore, the image of the point (4, 3) after a -90-degree rotation is (3, -4).
A 90 degree rotation is a quarter of a turn.
The answer will depend on whether the rotation is clockwise or anti-clockwise.
A turn from east to south clockwise involves a 90-degree rotation. Since a right angle is defined as a 90-degree angle, this turn consists of one right angle. Therefore, there is one right angle in a turn from east to south clockwise.
It is 1/4 of a turn
The answer will depend on whether the rotation is clockwise or counterclockwise.
