What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, known as the center of rotation, by a specified angle in a specified direction.

What is the angle of rotation for a 180° clockwise rotation?

Back

The angle of rotation is 180°, which means the figure is turned halfway around the center of rotation.

How do you determine the new coordinates of a point after a 90° clockwise rotation?

Back

To rotate a point (x, y) 90° clockwise, the new coordinates will be (y, -x).

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation is in the direction of the hands of a clock, while counterclockwise rotation is in the opposite direction.

How do you find the angle of rotation when given original and rotated coordinates?

Back

You can find the angle of rotation by analyzing the change in coordinates and using trigonometric functions or geometric reasoning.

What is the rule for rotating a point 180° about the origin?

Back

The rule for rotating a point (x, y) 180° about the origin is to change both coordinates to their opposites: (-x, -y).

What is the significance of the center of rotation?

Back

The center of rotation is the fixed point around which a figure is rotated, and it remains unchanged during the rotation.
