Unit 1 Transformations

Determine how to translate triangle ABC to triangle A'B'C' ?

• (x + 2, y - 5)

• (x + 2, y - 9)

• (x - 2, y - 9)

• (x - 2, y + 9)

What is the Algebraic Notation for this Reflection?

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

When you reflect over the y axis, what stays the same?

• x stays the same

• y stays the same

• z stays the same

• q stays the same

Identify the transformation from ABCD to A'B'C'D'.

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

Choose the correct scale factor:

• 2
• 3
• 1/3
• 1/2

If the scale factor is less than one, the new figure will be

• an enlargement
• a reduction
• a scale factor
• bigger

The Pre-Image was reflected over the y-axis then reflected over the x-axis to get the final image. What single transformation will map the Pre-Image to the Image?

• Rotate 180˚ about the origin.

• Reflect over the line y = x.

• Translate -4 units vertically and -9 units horizontally.

• Rotate 90˚ about the top point.

When you translate, (x-4,y) will move _____.

• 4 units right
• 4 units left
• 4 units up
• 4 units down

Identify the transformation from C to D.

• 90^o Clockwise Rotation about the origin

• 180^o Rotation about the origin

• 270^o Clockwise Rotation about the origin

• 360^o Rotation about the origin

Identify the transformation.

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