Transformations Practice

Match the following TRANSLATIONS

• left 5, up 2

• (x, y)-->(x-3, y+4)

• right 3, down 4

• (x, y)-->(x+5, y+2)

• left 3, down 4

• (x, y)-->(x+3, y-4)

• left 3, up 4

• (x, y)-->(x-5, y+2)

• right 5, up 2

• (x, y)-->(x-3, y-4)

A reflection over the x-axis causes the ​ (a)   to stay the same and the ​ (b)   to switch.

The algebraic representation is ​ (c)  

• x-value
• y-value
• (x, y)-->(x, -y)
• (x, y)-->(-x, y)

A reflection over the y-axis causes the ​ (a)   to stay the same and the ​ (b)   to switch.

The algebraic representation is ​ (c)  

• y-value
• x-value
• (x, y)-->(-x, y)
• (x, y)-->(x, -y)

Match the following TRANSLATIONS

• right 1, up 6

• (x, y)-->(x-1, y+6)

• left 3, down 1

• (x, y)-->(x-3, y-1)

• right 1, down 6

• (x, y)-->(x-3, y+1)

• left 3, up 1

• (x, y)-->(x+1, y+6)

• left 1, up 6

• (x, y)-->(x+1, y-6)

Translations are the only type of transformation that ​ (a)   .

• add or subtract
• multiply
• switch spots

• x-value
• right
• switches signs
• y-value
• left
• stays the same

• y-value
• left
• switches signs
• stays the same
• x-value
• right

Match the following transformations:

• (x, y)-->(x, -y)

• (x, y)-->(-x, y)

• Reflection over y-axis

• (x, y)-->(y, -x)

• (x, y)-->(-y, x)

• (x, y)-->(-x, -y)

• Reflection over x-axis

Which of the following does NOT preserve congruence?

• Dilations

• Translations

• Reflections

• Rotations

Match the following

• (x, y)-->(x+2, y+2)

• Reflection over x-Axis

• (x, y)-->(x, -y)

• (x, y)-->(-x, -y)

• Translation

• (x, y)-->(2x, 2y)

• Dilation

• (x, y)-->(-x, y)

• Reflection over y-Axis
