rotates an object in the clockwise direction
|
|
|
rotates an object in the counter-clockwise direction
|
|
|
Both of the above
|
|
|
None of the above
|
Detailed explanation-1: -The positive value of the pivot point (rotation angle) rotates an object in a counter-clockwise (anti-clockwise) direction. The negative value of the pivot point (rotation angle) rotates an object in a clockwise direction. When the object is rotated, then every point of the object is rotated by the same angle.
Detailed explanation-2: -Explanation: A positive value for the rotation angle defines counterclockwise rotations about the pivot point. Explanation: The rotation transformation is also described as a rotation about a rotation axis that is perpendicular to the xy plane and passes through the pivot point.
Detailed explanation-3: -In physics, the counterclockwise direction is defined as positive and clockwise is negative for rotational variables.
Detailed explanation-4: -Clockwise motion (abbreviated CW) proceeds in the same direction as a clockâs hands: from the top to the right, then down and then to the left, and back up to the top. The opposite sense of rotation or revolution is (in Commonwealth English) anticlockwise (ACW) or (in North American English) counterclockwise (CCW).
Detailed explanation-5: -Angles of Rotation Positive angle measures represent a counterclockwise rotation while negative angles indicate a clockwise rotation.
