Rotations

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle in a specific direction.

The center of rotation is the fixed point around which a figure is rotated.

A full rotation is 360 degrees.

A 90-degree clockwise rotation turns the figure to the right, moving each point to a new position that is 90 degrees around the center.

A 90-degree counterclockwise rotation turns the figure to the left, moving each point to a new position that is 90 degrees around the center.

The result is (-x, -y), meaning both coordinates change their signs.

A 270-degree counterclockwise rotation is equivalent to a 90-degree clockwise rotation.

Rotating a figure 0 degrees means the figure remains in its original position.

You can determine the angle of rotation by measuring the angle formed between the original position and the new position of the figure.

Rotation turns a figure around a point, while reflection flips a figure over a line, creating a mirror image.
