Exploring Transformational Geometry: Translations, Rotations, and Reflections

What is the first step in performing a translation of a geometric figure?

• Translate each point individually according to specific criteria.

• Draw a new figure from memory.

• Use a computer program to automatically translate.

• Move the entire shape at once.

What is the result of reflecting a point one block above the reflection line?

• One block to the right of the line.

• One block below the line.

• Two blocks above the line.

• Remains in the same position.

What is the purpose of using a cursive 'L' for the reflection line?

• It's a traditional method with no specific reason.

• To indicate a longer line.

• Because it's easier to draw.

• To differentiate it from the number one.
