Rotation on Coordinate Plane

Front

What is rotation in the coordinate plane?

Back

Rotation is a transformation that turns a figure around a fixed point, called the center of rotation, by a certain angle in a specified 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 degrees clockwise rotation look like?

Back

A 90 degrees clockwise rotation turns a point or figure to the right, moving it to a new position.

Front

What does a 90 degrees counterclockwise rotation look like?

Back

A 90 degrees counterclockwise rotation turns a point or figure to the left, moving it to a new position.

Front

What is the result of a 180 degrees rotation around the origin?

Back

A 180 degrees rotation around the origin flips the figure to the opposite side of the origin.

Front

How do you find the coordinates after a 90 degrees clockwise rotation?

Back

For a point (x, y), the new coordinates after a 90 degrees clockwise rotation are (y, -x).

Front

How do you find the coordinates after a 90 degrees counterclockwise rotation?

Back

For a point (x, y), the new coordinates after a 90 degrees counterclockwise rotation are (-y, x).

Front

What happens to the coordinates after a 180 degrees rotation?

Back

For a point (x, y), the new coordinates after a 180 degrees rotation are (-x, -y).

Front

What is the effect of a 360 degrees rotation?

Back

A 360 degrees rotation returns the figure to its original position.

Front

How can you determine if two figures are rotations of each other?

Back

Two figures are rotations of each other if one can be obtained from the other by rotating it around a point.
