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 angle of rotation for a 90 degrees clockwise rotation?

Back

A 90 degrees clockwise rotation turns the figure 90 degrees to the right.

Front

What happens to a point (x, y) when it is rotated 90 degrees clockwise about the origin?

Back

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

Front

What is the result of rotating the point A(-4, 4) 90 degrees clockwise?

Back

The new coordinates will be (4, 4).

Front

True or False: A 360 degrees rotation puts the image or the point back to its original position.

Back

True.

Front

What is the term used to describe a rotation?

Back

Turn.

Front

If a triangle with vertices A(-2, 1), B(2, 4), and C(4, 2) is rotated 90 degrees clockwise, what are the new vertices?

Back

A'(1, -2), B'(4, -2), C'(2, -4).

Front

What is the angle of rotation for a 270 degrees clockwise rotation?

Back

A 270 degrees clockwise rotation is equivalent to a 90 degrees counterclockwise rotation.

Front

How do you determine the angle of rotation for a transformation?

Back

The angle of rotation can be determined by measuring the angle between the original position and the new position of the figure.

Front

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

Back

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