Transformations Review

Match the transformation shown to the correct description

• Translation

• 

• Rotation

• 

• Dilation

• 

• Reflection

• 

The only transformation that does NOT preserve congruency is dilations.

• True

• False

Apply the rule

( x , y ) ---> ( x-5 , y-2 )

to the triangle shown

Rectangle GHIJ was translated using the rule

( x , y) ---> (​ (a)   , ​ (b)   )

• x - 7

• y + 4

• y - 7

• x + 4

• x + 7

• y - 4

The coordinates shown represent translated points. Draw a line to connect the coordinates with

the correct description and draw a line to connect the algebraic representation of the translation.

A reflection ​ (a)   a figure over a line of ​ (b)   in order to create a ​ (c)   image.

Each reflected point of the figure should be the same ​ (d)   from the line of reflection on the ​ (e)   side.

• flips

• reflection

• mirror

• distance

• opposite
