Geometry Transformations

Translations, reflections and rotations are all known as ________________________.

• Geometry
• Transformations
• Congruent

When you translate, you ______ a number to x and y.

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

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'.

• 90^o clockwise rotation
• 90^o counter clockwise rotation
• Reflection across the y-axis
• Reflection across the x-axis

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 shown in the graph.

• Reflect over x-axis
• Reflect over y-axis
• Rotate 270 degrees CCW
• Rotate 90 degress CCW

The point that is to be transformed is called the:

• Pre-Image
• Image
• Post-Image
• Transformation

After being transformed the new point is called a(n):

• Pre-Image
• Post Image
• Transformed
• Image

What would the new point be if you rotated the point (3,-5) 270° clockwise?

• a.  (-3,-5) 
• b.  (-5,-3) 
• c.  (5,3)

Which of the following describes the sequence of transformations shown?

• Reflect across the x-axis and then rotate -90 degrees around the origin

• Rotate -90 degrees around the origin and then translate down.

• Reflect across the x-axis and then reflect across the y-axis.

• Translate up and then rotate 90 degrees about the origin.
