Rigid Motion Transformations Rules

The image of the point (2, -7) reflected over the what line would be (-7, 2).

• x - axis

• y - axis

• y = x

• x = 1

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)

• (-1, 5)

What are the series of rigid motions that would map ∆ABC onto ∆A''B''C''?

• a reflection followed by a rotation

• a reflection followed by a translation

• a translation followed by a rotation

• a translation followed by a reflection

Identify the transformation from C to D.

• 90^o Clockwise Rotation

• 180^o Rotation

• 270^o Clockwise Rotation

• 360^o Rotation

Identify the angles of rotation that maps the image to itself.

• multiples of 72°

• multiples of 180°

• multiples of 144°

• multiples of 45°

Identify the correct picture which represents a 90^o clockwise rotation about the origin.

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

Point (-5,2) is reflected over the y axis.  Where is the new point located?

• (5,2)

• (-5,-2)

• (-5,2)

• (5,-2)

Write a rule for the translation.

•  (x -1, y  + 2)

•  (x -2, y  + 1)

•  (x +2, y  - 1)

• (x +1, y  -  2)
