Transformation Dilation

A dilation is which of the following: 

• An enlargement

• A reduction

• Either an enlargement or a reduction

• Neither an enlargement or a reduction

What Transformation is visible?

• Reflection

• Translation

• Rotation

• Dilation

Determine how to translate triangle A'B'C' to triangle ABC.

• (x+2, y-5)

• (x+2, y-9)

• (x-2, y-9)

a transformation that changes the size of a figure, but not the shape

• translation

• rotation

• reflection

• dilation

If the scale factor is greater than 1, the dilation is...

• an enlargement

• a rotation

• a translation

• a reduction

If the scale factor is less than 1, the dilation is...

• an enlargement

• a translation

• a rotation

• a reduction

Enlargement or reduction?  Find the scale factor!

• It's a reduction; the scale factor is 2.

• It's an enlargement; the scale factor is 2.

• It's an enlargement; the scale factor is 1/2.

• It's a reduction; the scale factor is 1/2.

Triangle ABC is going to be translated. How is ABC being translated if the rule (x,y) --> (x+3, y-2) is used?

• 3 up and 2 left

• 3 right and 2 down

• 3 left and 2 up

• 3 right and 2 up 

How is triangle ABC being translated to triangle A'B'C'?

• (x, y) --> (x - 8, y + 3 )

• (x, y) -->(x - 4, y - 9) 

• (x, y) --> (x + 8, y - 3) 

• (x, y) --> (x+ 4, y - 9) 

If you were to rotate ABCD 180°  about the origin, what would the coordinate of A' be?

• (-5, 5)

• (-3, -5)

• (-5, 3)

• (-3, 3)
