Rotations

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point called the center of rotation.

Front

What is the center of rotation?

Back

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

Front

What does counterclockwise rotation mean?

Back

Counterclockwise rotation means turning a figure in the opposite direction of the hands of a clock.

Front

What does clockwise rotation mean?

Back

Clockwise rotation means turning a figure in the same direction as the hands of a clock.

Front

What is the angle of rotation?

Back

The angle of rotation is the measure of the degree through which a figure is rotated.

Front

What is a preimage?

Back

A preimage is the original figure before any transformation, such as rotation.

Front

What is an image in geometry?

Back

An image is the resulting figure after a transformation, such as rotation.

Front

If a triangle is rotated 90° clockwise, what happens to its orientation?

Back

The triangle's orientation changes, and its vertices move to new positions based on the rotation.

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a figure around a point, while a reflection flips a figure over a line.

Front

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

Back

To find the new coordinates, apply the rotation rules based on the angle and direction of rotation.
