Rotation, in the plane of the grid, through 180 degrees.
The size does not change and the orientation is altered by the extent of the rotation.
They change the orientation.
Yes, it does.
The relationship between the orientation of the image and preimage depends on whether the transformation is a reflection or a rotation (or both).
All three are preserved.
These are examples of transformations of shapes which preserve their size.
Optical rotation is the turning plane of linearly polarized light as it travels through certain materials. Specific rotation is the property of a chemical compound as the change in orientation of a plane of light.
This is a transformation which could be a rotation, translation or reflection.
Precession is a change in the orientation of the rotational axis of a rotating body. It can be used to describe the rotation of everything from a simple gyroscope to the rotation of a planet. 420
These are transformations that do not change the shape or size, only its location (translation) or orientation (rotation).
A person can turn off orientation on a Nokia Lumia 610 by turning off auto rotation in the phone's settings. It will be located under the display settings.
