Math 1A Rigid Transformations

A slide is also called a _________.

• Translation
• Reflection
• Rotation
• Transformation

A turn is also called a ___________.

• Translation
• Reflection
• Rotation
• Transformation

A type of transformation where a figure is “flipped” over a line of symmetry.

• rotation
• translation
• dilation
• reflection

Name the transformation.

• Translation
• Reflection
• Rotation

Identify the transformation.

• Reflection across y axis
• Reflection across x-axis
• 180 Rotation
• Translation 2 units down

Write a rule for the translation.

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

What is the algebraic notation of a figure is Translated 9 units right and 3 units down?

• (x, y) --> (x - 9, y + 3)
• (x, y) --> (x + 9, y - 3)
• (x, y) --> (x + 3, y - 9)
• (x, y) --> (9x, 3y)

Translations, reflections and rotations are all known as ________________________.

• Geometry
• Transformations
• Congruent
