Transformations

What transformation is happening?
(x, y) ----> (x + 2, y - 3) 

• slide up 2, left 3
• slide right 2, up 3
• slide right 2, down 3
• slide left 3, right 2

Reflect the point (2, -4) over the y-axis.

• (-4, 2)
• (-2, 4)
• (-2, -4)
• (2, 4)

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

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

Which rule would dilate shows a scale factor of 4

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

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)

Is the picture being reflected in the y-axis or x-axis?

• y-axis
• x-axis

Identify the transformation from C to D.

• 90^o Clockwise Rotation
• 180^o Rotation
• 270^o Clockwise Rotation
• 360^o Rotation

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)

Does the transformation shown preserve congruence and/or orientation?

• Congruence yes, Orientation yes
• Congruence No, Orientation No
• Congruence No, Orientation yes
• Congruence Yes, Orientation No

Congruent geometric figures have the:

• Same size
• Sides Equal
• Same Size and Same Shape
• Angles Equal
