The answer depends on the location of A and C. Without that information the question cannot be answered.
The answer will depend on whether the rotation is clockwise or counterclockwise.
Rotation preserves shape - therefore the angle before the rotation equals the angle after the rotation.
You went 360o in the same direction, so you end up with a circle.
In Excel it is between -90 deg and +90 deg.
The answer depends on the centre of rotation. A rotation cannot be described without specifying the centre of rotation.
It is (-1, 6).
The answer will depend on whether the rotation is clockwise or counterclockwise.
The answer will depend on whether the rotation is clockwise or counterclockwise.
(-1, -4) rotated 90 degrees anticlockwise
If B was (x, y) then B' is (-y, x).
false
The rule for a rotation by 180° about the origin is (x,y)→(−x,−y) .
Rotation preserves shape - therefore the angle before the rotation equals the angle after the rotation.
(x,y)-> (-y,x)
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.
You went 360o in the same direction, so you end up with a circle.
In Excel it is between -90 deg and +90 deg.
