Geo- Unit 2 Review - Before Final

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

If you were to rotate ABCD 90° counterclockwise about the origin, what would the coordinate of A' be?

• (-5, 5)
• (-3, 5)
• (-5, 3)
• (-3, 3)

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

Which answer shows a reflection across the y-axis?

• a
• b
• c
• d

Which of the following are congruence transformations?

• Rotations
• Translations
• Reflections
• All Three

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.

What is the sequence of transformations for the image given? 

• Reflect over the x-axis, translate (x+8,y)
• Reflect over the x-axis then translate (x+6, y)
• Reflect over the y-axis then (x+1, y+1)
• Translate down 4 (y-4) and to the right 5 (x+5)

Write a rule for the translation.

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

Point (-5,2) is reflected over the y axis. Where is the new point located? (Hint: Draw the x and y axes)

• (5,2)

• (-5,-2)

• (-5,2)

• (5,-2)

Identify the transformation.

• Reflection across y-axis
• 90 Rotation counter clockwise
• Translation 5 units left, 1 unit up.
• Translation 5 units right, 1 unit down
