Identifying Transformations

What is a rotation in geometry?

• A transformation that flips a figure over a line.

• A transformation that slides a figure in a straight line.

• A transformation that changes the size of a figure.

• A transformation that turns a figure around a point.

What remains the same during a rotation?

• The color of the figure.

• The position of the figure.

• The orientation of the figure.

• The shape and size of the figure.

What is the angle of rotation?

• The radius of the circle formed by the rotation.

• The direction the figure moves.

• The degree measure between the pre-image and image.

• The distance the figure moves.

How are clockwise rotations represented?

• With positive angle measures.

• With negative angle measures.

• With a prime symbol.

• With a double prime symbol.

What is the result of rotating a point about P by -30°?

• The point moves 30° in a clockwise direction.

• The point moves 30° in a counterclockwise direction.

• The point moves 60° in a clockwise direction.

• The point does not move.

What is the common notation for the image of a point after a transformation?

• The original letter in a different color.

• The original letter with a subscript.

• The original letter with a dash.

• The original letter with a prime symbol.

What is the default direction for rotation if not specified?

• Counterclockwise

• Away from the center

• Clockwise

• Towards the nearest quadrant

How is a -120° rotation about point P represented?

• 60° counterclockwise rotation

• 60° clockwise rotation

• 120° counterclockwise rotation

• 120° clockwise rotation

What does a prime symbol next to a point's letter indicate?

• The point after transformation.

• The center of rotation.

• The point before transformation.

• The midpoint of the transformation.

What happens to the distance of each point from the center during a rotation?

• It becomes zero.

• It increases.

• It remains the same.

• It decreases.
