Rigid Transformations

Translations, rotations, and reflections are three different types of what?

• Transformations
• Geometry
• Vectors
• Shapes

Which set of directions describes the translation from ABCD to A'B'C'D'?

• Down 6, left 3
• Down 3, right 6
• Up 3, left 6
• Up 6, right 3

Which answer shows a reflection across the y-axis?

• a
• b
• c
• d

Point (-5,2) is reflected over the y axis.  Where is the new point located?

• (5,2)
• (-5,-2)
• (-5,2)
• (5,-2)

Describe the transformation.

• translation: right 3 and down 2
• felfection across y=-x
• rotation 180 degrees about the origin
• rotation 90 degrees clockwise about the origin

Identify the correct picture which represents a 90^o clockwise rotation about the origin.

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

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

• (-5, 5)
• (-3, -5)

• Multiply or divide
• Add or multiply
• Subtract or divide
