Intro to Transformations and Translations

What transformation is shown here?

• Translation

• Rotation

• Reflection

• Dilation

Tell whether each statement is true or false.

Groups:

(a) True

,

(b) False

• In reflection, the orientation of the vertices is different.

• In translations, the orientation of the figure is different.

• With rotations, the orientation of the figure stays the same.

• In reflections, the size of the figure is different.

• With dilations, the size of the figure stays the same.

• With dilations, the orientation of the figure stays the same.

• In translations, the size of the figure stays the same.

• With rotations, the orientation of the vertices stays the same.

Write the translation rule shown on the left.

• slide up 2, left 3

• slide right 2, up 3

• slide right 2, down 3

• slide left 3, right 2

Which figure is the pre-image?

• the blue one

• the pink one

• both are

• neither are

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

• up 3, left 8

• up 9, left 4

• down 3, right 8

• down 9, right 4

In a translation, the preimage and image are ___________.

• congruent

• similar

• different

• red

How is trapezoid ABCD translated to trapezoid A'B'C'D'?

• (x, y) --> (x + 5, y + 8)

• (x, y) --> (x + 5, y - 8)

• (x, y) --> (x - 8, y + 5)

• (x, y) --> (x - 8, y - 5)

Write a rule for the translation.

•  (x -1, y  + 2)

•  (x -2, y  + 1)

•  (x +2, y  - 1)

• (x +1, y  -  2)
