• multiples of 72°

• multiples of 180°

• multiples of 144°

What sequence of transformations will map trapezoid A to its image A'?

• Reflection across vertical line, then translation downwards

• Rotation 180 degrees, then reflection over x-axis

• Reflection across x-axis, then translation upwards

• Rotation 180 degrees, then reflection over y-axis

Which of the following describes the sequence of transformations shown?

• Reflect across the x-axis and then rotate 90 degrees clockwise around the origin

• Rotate 90 degrees clockwise around the origin and then translate down.

• Reflect across the x-axis and then reflect across the y-axis.

• Translate up and then rotate 90 degrees counterclockwise about the origin.

Determine the coordinates of X' if point X is translated 3 units to the left and 9 units down.

• (-4, 4)

• (-10, 2)

• (-4, -5)
