Rigid Motion Transformations

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

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

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)

Write a rule for the translation.

•  (x -1, y  + 2)

•  (x -2, y  + 1)

•  (x +2, y  - 1)

• (x +1, y  -  2)

What is the angle of rotation would map the figure onto itself? (Select all that apply)

• 60 degrees

• 120 degrees

• 180 degrees

• 240 Degrees

Reflect triangle ABC across the y-axis:

• A' (-2, 5) B' (3, 1) C' (3, -3)

• A' (2, -5) B' (-3, -1) C' (-3, 3)

• A' (-2, -5) B' (-3, 1) C' (3, 3)

• A' (-2, 5) B' (3, -1) C' (3, -3)

If P is the pre-image and Q the image, select the correct segment that translates P to Q.
