Understanding Transformations

The video tutorial introduces the concept of transformations in geometry, comparing them to transformers that change form. It explains the difference between pre-image and image, and describes four types of transformations: translation, reflection, rotation, and dilation. Real-world examples are provided, such as conveyor belts and mirrors. The tutorial also covers congruence and orientation, explaining how they relate to transformations. Finally, it analyzes specific transformations to determine congruence and orientation changes.

What is the term used for the original figure before a transformation?

• Transformed figure

• Pre-image

• Image

• Post-image

Which transformation involves sliding a figure to a new position?

• Reflection

• Rotation

• Translation

• Dilation

What transformation is similar to looking in a mirror?

• Rotation

• Reflection

• Translation

• Dilation

Which transformation involves turning a figure around a point?

• Translation

• Dilation

• Reflection

• Rotation

What happens to a figure during a dilation?

• It flips over a line

• It slides to a new position

• It turns around a point

• It changes size

Which real-world example is similar to a translation?

• A mirror reflection

• A conveyor belt

• A pupil dilating

• A wheel turning

What does congruence mean in transformations?

• Different shape

• Different size

• Same orientation

• Same size and shape

How does the orientation of a figure change in a reflection?

• It stays the same

• It flips

• It enlarges

• It rotates

Which transformation is not congruent due to a change in size?

• Dilation

• Reflection

• Rotation

• Translation
