Transformations Review

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

• Reflection, then translation down 6 unites

• Rotation, then translation up 5 units

• Reflection, then rotation 90 degrees CCW

• Rotation, then dilation by 2

Match the terms with their definitions.

• A transformation that turns a figure around a point.

• Rotation

• A transformations that changes the size

• Reflection

• A transformation that flips a figure across a line.

• Translation

• A transformation that slides a figure.

• Dilation

Which transformation is shown?

• Translation

• Reflection over the x-axis

• Reflection over the y-axis

• 90^o counterclockwise rotation

Which transformation is shown?

• Translation

• Reflection over the x-axis

• Reflection over the y-axis

• 180^o rotation

A point is translated 3 units left and 4 units up. What is the correct translation rule?

• T(x,y)→(x+3,y+4)
• T(x,y)→(x-3,y-4)
• T(x,y)→(x+3,y-4)
• T(x,y)→(x-3,y+4)

If a point is at (-10,6), and it gets translated horizontally -6 units and vertically 5 units, where is it's new location?

• (-5,0)
• (-16,1)
• (-15,0)
• (-16,11)

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

Write the rule for this translation:

Slide 2 right and 3 up.

• (x, y)---->(x + 3, y + 2)

• (x, y)-----> (x+2, y + 3)

• (x, y)----> (x - 2, y + 3)

Identify the transformation from ABC to A'B'C'.

• (x+8, y+4)
• (x-8, y-4)
• (x+4, y+8)
• (x-4, y-8)

An object containing the point (-5,11) was moved to the location (0,4). Which choice best describes the translation?

• right 5, down 7

• left 5, up 7

• right 7, down 5

• left 7, up 5
