3.7 translations

Explanation:

Step1: Recall the definition of translation

A translation is a transformation that slides a figure without rotating or flipping it.

Step2: Analyze each pair

• 9: The red figure is flipped (rotated \(180^{\circ}\) in a sense related to orientation), so it is not a translation.
• 10: The red figure is in the same orientation and can be obtained by sliding the blue figure, so it is a translation.
• 11: The red figure is flipped (mirror - like), so it is not a translation.
• 12: The red figure is in the same orientation and can be obtained by sliding the blue figure, so it is a translation.
• 13: The red figure is in the same orientation and can be obtained by sliding the blue figure, so it is a translation.
• 14: The red figure is flipped (mirror - like), so it is not a translation.

Answer:

1. Not a translation; 10. Translation; 11. Not a translation; 12. Translation; 13. Translation; 14. Not a translation.
