Performing transformations

Describe the transformation.

• translation by (x - 1, y + 6)

• reflection across x = -2

• translation by (x + 6, y - 1)

• reflection across y = -2

Which would be the best rule for the transformation shown?

• translation
• reflection across the y axis
• reflection across the x axis

What is the sequence of transformations?

• Reflect over the y then reflect over the x

• Reflect over the x then reflect over the y

• Translate 4 units then rotate 90˚

• Rotate 90˚ then reflect over the x

• Rotation of 180 degrees

Transformations

Marcy transformed figure 1 to obtain figure 2, then she transformed figure 2 to obtain figure 3. Which transformations can be the ones Marcy used?

• a reflection across the y-axis and then a reflection across the x-axis

• a rotation 90° clockwise and then a translation left

• a translation left and then a reflection across the x-axis

• a translation left and then a translation down

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

What sequence of transformations will get you from shape BCD to shape B"C"D" in two steps?

• Rotation, then translation

• Reflection, then Rotation

• Translation, then Reflection

• Zach

• Naomi

• Both are correct

• Both are incorrect

Identify the transformation from ABCD to A'B'C'D'.

• 90^o rotation
• Translation
• Reflection across the x-axis

If you rotate point A(-3,4) 180 degrees clockwise and then rotate it again 90 degrees counter clockwise what would be the coordinates of A"?

• (-3,-4)
• (-4,-3)
• (3,-4)
• (4,3)

what are the two rigid motions are performed 

• translation then reflection
• reflection then translation
• rotation 90^o  counter clock then translation
