Geo3.3 Rotations -Trasformations

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 specified angle in a specified direction.

Front

What is the angle of rotation for a 90° clockwise rotation?

Back

A 90° clockwise rotation turns a figure 90 degrees to the right around the center of rotation.

Front

What are the coordinates of a point (x, y) after a 90° counterclockwise rotation about the origin?

Back

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

Front

What are the coordinates of a point (x, y) after a 180° rotation about the origin?

Back

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

Front

What are the coordinates of a point (x, y) after a 270° clockwise rotation about the origin?

Back

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

Front

In which quadrant will a point be after a 270° clockwise rotation if it starts in quadrant 1?

Back

The point will move to quadrant 4.

Front

In which quadrant will a point be after a 90° counterclockwise rotation if it starts in quadrant 3?

Back

The point will move to quadrant 2.

Front

What is the result of rotating the point (3, 4) 90° counterclockwise about the origin?

Back

The new coordinates will be (-4, 3).

Front

What is the result of rotating the point (-3, 5) 90° clockwise about the origin?

Back

The new coordinates will be (5, 3).

Front

What is the result of rotating the point (4, 3) 180° about the origin?

Back

The new coordinates will be (-4, -3).
