PA Transformations Practice TEST

The original figure prior to a transformation.

• Pre-image
• Image

What transformation is happening?
(x, y) ----> (x + 2, y - 3) 

• translation up 2, left 3

• translation right 2, up 3

• translation right 2, down 3

• translation left 3, right 2

What is the algebraic notation of a figure is Translated 6 units right and 5 units up?

• (x, y) --> (x - 6, y + 5)
• (x, y) --> (x + 6, y + 5)
• (x, y) --> (x + 5, y - 6)
• (x, y) --> (6x, 5y)

Which transformation(s), no matter which one you do, will the resulting image be congruent? (select all that apply)

• translation

• reflection

• rotation

• dilation

Similar figures are figures that are the SAME shape, but a DIFFERENT size.

Which one of the following transformations will produce a similar figure?

• translation

• dilation

• rotation

• reflection

Translations keep

• both congruence and orientation
• only congruence
• only orientation
• neither

Dilations keep

• both congruence and orientation
• only congruence
• only orientation
• neither

Reflections keep

• both congruence and orientation
• only congruence
• only orientation
• neither

A transformation is applied to create a new figure. Which transformation does not preserve orientation?

• A dilation with a scale factor of (⅕x, ⅕y)
• A translation 4 units up
• A dilation by a scale factor of 5
• A rotation 90° clockwise

When you reflect a point over the Y axis, the ____________ changes.

• X coordinate

• Y coordinate
