Transformations Review Geometry

Name the transformation.

• Translation

• Reflection

• Rotation

The mathematical term for the line that you reflect a shape over is the...

• Mirror

• Reflective tape

• Line that you reflect over

• Line of reflection

After a figure has been transformed, we call the new figure the...

• Image

• Different shape

• Figure that moved

• Prime

Describe the transformation:

(x, y) -> (x-2, y+7)

• Translation 2 units to the left & 7 units up

• Translation 2 units to the left & 7 units down

• Translation 2 units to the right & 7 units up

• Translation 2 units to the right & 7 units down

Write a rule for the translation.

•  (x -1, y  + 2)

•  (x -2, y  + 1)

•  (x +2, y  - 1)

• (x +1, y  -  2)

Identify the transformation from ABC to A'B'C'.

• Reflection across the x-axis

• Reflection across the y-axis

• 90^o clockwise rotation

• 90^o counterclockwise rotation

In translations, the image and the pre-image are always

• parallel

• next to each other

• congruent

• opposite

A turn is also called a ___________.

• Translation

• Reflection

• Rotation

• Transformation

Select the correct transformation rule.

• translation (x + 4, y + 2)

• rotation 90 degrees CCW

• rotation 90 degrees CW

• reflection across x = - 1

Describe a sequence of transformations that maps figure A onto figure B.

• translation 4 units right followed by a reflection across the x-axis

• reflection across the x-axis followed by a reflection across the y-axis

• reflection across the y-axis followed by a translation 6 units down

• 90° counter-clockwise rotation about the Origin followed by a reflection across the y-axis
