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

• Pre-Image
• Post Image
• Transformed
• Image

The point that is to be transformed is called the:

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

What does congruent mean?

• Same shape, different size
• Not same shape, or size
• Same size, same shape

Match the terms with their definitions.

• A transformation that slides a figure.

• Reflection

• A transformation that turns a figure around a point.

• Rotation

• A transformation that flips a figure across a line.

• Translation

Match the following

• Enlargement/Stretch

• Scale Factor > 1

• Reduction/Shrink

• Scale Factor < 1

• Congruent

• Scale Factor = 1

Match the Transformations.

• Rotation

• 
• Reflection

• 
• Translation

• 

Tell whether the two figures are congruent.

• Yes, same size and same shape
• No, same shape but different sizes
• No, different size and different shapes

Tell whether the two figures are congruent.

• Yes, same size and same shape
• No, same shape but different sizes
• No, different size and different shapes

Which transformation(s) ONLY create(s) congruent figures?

Select all that apply.

• Dilation
• Translation

• Reflection

• Rotation

What is the sequence of transformations?

• Reflect over the y-axis then reflect over the x-axis
• Reflect over the x-axis then reflect over the y-axis
• Translate 4 units then rotate 90˚ counter-clockwise about the origin
• Rotate 90˚ counter-clockwise about the origin then reflect over the x
