Unit 2: Transformations Reflection Quiz

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

• y-axis
• x-axis

Reflect a figure over the y-axis- 

• Change the x-coordinate
• Change the y-coordinate

Reflect a figure over the x-axis- 

• Change the x-coordinate
• Change the y-coordiate

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

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

∆QRS contains the points: Q(4, 2) R(5, 1) S(3,7). If the triangle is reflected across the y-axis, what will S' be?

• S'(3, 7)
• S'(-3, 7)
• S'(-3, -7)
• S'(3, 7)

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

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

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

Name the transformation.

• Translation
• Reflection
• Rotation

The point that is to be transformed is called the:

• Pre-Image
• Image
• Post-Image
• Transformation

After being transformed the new point is called a(n):

• Pre-Image
• Post Image
• Transformed
• Image
