Rotations in the Coordinate Plane !!!

Front

What is a rotation in the coordinate plane?

Back

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

Front

What is the range of degrees for a rotation in the coordinate plane?

Back

0 to 360 degrees.

Front

How do you perform a 90-degree counterclockwise rotation on a point (x, y)?

Back

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

Front

How do you perform a 90-degree clockwise rotation on a point (x, y)?

Back

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

Front

What are the coordinates of the image of point C(3, 6) after a positive 90-degree rotation?

Back

(-6, 3).

Front

What are the coordinates of the image of point E(-9, -8) after a clockwise 90-degree rotation?

Back

(-8, 9).

Front

What happens to a line segment when it is rotated 90 degrees clockwise?

Back

The line segment moves to a new location.

Front

In which direction does a clockwise rotation move?

Back

Same as the clock.

Front

What is the effect of a 180-degree rotation on a point (x, y)?

Back

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

Front

What is the center of rotation?

Back

The fixed point around which a figure is rotated.
