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, by a certain angle in a specific direction.

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 a 90° clockwise rotation look like?

Back

A 90° clockwise rotation turns a figure 1/4 of a full turn to the right.

Front

What does a 180° rotation do to a figure?

Back

A 180° rotation flips a figure to the opposite side, effectively turning it upside down.

Front

How many degrees are in a full rotation?

Back

There are 360 degrees in a full rotation.

Front

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation moves in the same direction as the hands of a clock, while counterclockwise rotation moves in the opposite direction.

Front

If a point (x, y) is rotated 90° clockwise, what are the new coordinates?

Back

The new coordinates will be (y, -x).

Front

If a point (x, y) is rotated 180°, what are the new coordinates?

Back

The new coordinates will be (-x, -y).

Front

If a point (x, y) is rotated 270° clockwise, what are the new coordinates?

Back

The new coordinates will be (-y, x).

Front

What is the angle of rotation for a full turn?

Back

The angle of rotation for a full turn is 360 degrees.
