To determine whether the shapes in each pair are translations of each other, we need to understand what a translation is. A
translation is a type of geometric transformation where every point of a shape is moved the same distance in the same direction. This means:
1. The shape does not change its size or orientation.
2. The shape does not rotate or flip.
3. The shape simply shifts to a new position.
Let's analyze each pair of shapes step by step:
---
Pair (a):
- The two parallelograms are identical in size and orientation.
- They are simply shifted horizontally and vertically.
- There is no rotation or flipping.
-
Conclusion: This is a translation.
---
Pair (b):
- The two rectangles are identical in size and orientation.
- They are simply shifted horizontally and vertically.
- There is no rotation or flipping.
-
Conclusion: This is a translation.
---
Pair (c):
- The two trapezoids are identical in size and orientation.
- They are simply shifted horizontally and vertically.
- There is no rotation or flipping.
-
Conclusion: This is a translation.
---
Pair (d):
- The two shapes are different: one is a square, and the other is a diamond (rhombus).
- Even though they might look similar, they are not the same shape.
-
Conclusion: This is
not a translation.
---
Pair (e):
- The two shapes are identical in size and orientation.
- However, they are rotated relative to each other.
- Translation does not involve rotation.
-
Conclusion: This is
not a translation.
---
Pair (f):
- The two triangles are identical in size and orientation.
- They are simply shifted horizontally and vertically.
- There is no rotation or flipping.
-
Conclusion: This is a translation.

Final Answers:
-
(a): translation
-
(b): translation
-
(c): translation
-
(d): not a translation
-
(e): not a translation
-
(f): translation
Circled Answers:
- Circle "translation" for pairs
(a), (b), (c), (f).
- Circle "not a translation" for pairs
(d), (e).
Final Answer:
\[
\boxed{\text{a: translation, b: translation, c: translation, d: not a translation, e: not a translation, f: translation}}
\]
