Transformation

Check all transformations that are an isometry

• Dilation

• Translation

• Rotation

• Reflection

What is the Algebraic Notation for this Reflection?

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

If the yellow curve has equation f(x)=x²,

• Then the blue curve is f(x) = x² - c
• Then the blue curve is f(x) = (x+c)²
• Then the blue curve is f(x) = (x-c)²
• Then the blue curve is f(x) = x² + c

Are the figures congruent?

(What type of transformation is shown?)

• NOT Congruent (dilation)

• NOT Congruent (translation)

• Congruent (dilation)

• Congruent (translation)

Reflect Point C over the y-axis:

• (-3, 2)
• (3,2)
• (-2,3)
• (3,0)

Rotation or Reflection

• Rotation
• Reflection
• translation

Identify the transformation from ABC to A'B'C'.

• (x+8, y+4)
• (x-8, y-4)
• (x+4, y+8)
• (x-4, y-8)

Which answer shows a reflection across the x-axis?

• d
• c
• b
• a

Describe the transformation:

(x, y) -> (-x, y)

• reflection across the x-axis

• reflection across the y-axis

• rotation 90 degrees clockwise

What kind of shift  is represented?

• up 1 unit
