Transformation

Which notation is used for the image?

• A

• A'

Determine which transformations form congruent figures and which form similar figures.

Groups:

(a) Congruent Figures

,

(b) Similar Figures

• Reflection

• Enlargement

• Rotation

• Translation

Place the transformations in order that they happened.

• Refection

• Translation

• Rotation

• Pre-image

Match the terms with their definitions.

• A transformation that turns a figure around a point.

• Rotation

• A transformation that flips a figure across a line.

• Translation

• A transformation that slides a figure.

• Reflection

Match the Transformations.

• 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

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

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

• (5,2)
• (-5,-2)
• (-5,2)
• (5,-2)

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)
• (x, y) → (x - 2, y + 3)
• (x, y) → (-x, -y)
• (x, y) → (x + 2, y - 3)

The rule for reflection over the y-axis is  
(x, y) --> _

• (-x, y)
• (x, -y)
• (y, x)
• (-y, x)
