Geometry Transformations and Reflections

Which answer shows a reflection across the y-axis?

• a

• b

• c

• d

Are the figures congruent?

(What type of transformation is shown?)

• Congruent (rotation)

• Congruent (reflection)

• NOT Congruent (rotation)

• NOT Congruent (reflection)

Identify the transformation.

• Translations

• Reflection

• Rotation

The transformation that flips

a figure across a line to form a

mirror image.

• Translation

• Reflection

• Rotation

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

• 90^o clockwise rotation

• 90^o counter clockwise rotation

• Reflection across the y-axis

• Reflection across the x-axis

Which of the following BEST describes the transformation?

• TRANSLATE 5 units down

• REFLECT over the x-axis

• ROTATE 90 degrees clockwise

• None of these

Describe the translation.

• Translate 3 up and 4 right

• Translate 3 down and 4 left

• Translate down 2

• Translate 1 up and 3 left

What is a rigid transformation?

• a transformation in

  which the size changes and shape of the figure does

  not change.

• a transformation in

  which the size and shape of the figure does

  not change.

• a transformation in

  which the shape changes and size of the figure does

  not change.

• a transformation in

  which the both the size and shape of the figure changes.

What properties stay the same on all rigid transformations?

• length of line

• measure of angle

• parallel lines

• orientation

Rigid Transformations will always maintain and preserve ALL of the following EXCEPT...

• size and shape

• angle measurements

• location and orientation

• area and perimeter

• parallel lines
