DOL: 12/18 Rotations

Front

What is a 180-degree rotation around the origin?

Back

A 180-degree rotation around the origin transforms a point (x, y) to (-x, -y).

Front

What is the result of rotating the point (-3, -4) 180 degrees around the origin?

Back

(3, 4)

Front

What is a 90-degree counterclockwise rotation around the origin?

Back

A 90-degree counterclockwise rotation transforms a point (x, y) to (-y, x).

Front

What is the result of rotating the point (7, 8) 90 degrees counterclockwise around the origin?

Back

(-8, 7)

Front

What is a 90-degree clockwise rotation around the origin?

Back

A 90-degree clockwise rotation transforms a point (x, y) to (y, -x).

Front

What is the result of rotating the point (-5, 8) 90 degrees clockwise around the origin?

Back

(8, 5)

Front

How do you determine the image of a point after rotation?

Back

Apply the appropriate rotation transformation based on the angle and direction of rotation.

Front

What is the image of point A(5, -3) after a 90-degree clockwise rotation?

Back

(5, -3) transforms to (-3, -5).

Front

What happens to the coordinates of a point when it is rotated 180 degrees?

Back

The coordinates change from (x, y) to (-x, -y).

Front

If a figure is rotated 90 degrees counterclockwise, what is the new position of point (x, y)?

Back

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