Transformations Guess This! Game {Translation, Reflection ... - Free Printable

I need to analyze this transformation worksheet. Let me work through each problem systematically by identifying what type of transformation is shown in each grid.

Looking at the grids, I can see triangles labeled with letters (like A, B, C, etc.) and their transformed versions marked with primes (A', B', C', etc.). I need to identify whether each transformation is a:
- Translation (slide)
- Reflection (flip)
- Rotation (turn)
- Or dilation (resize)

Let me go through each one carefully:

Row 1:
1. Triangle A → A': The triangle appears to be reflected across a vertical line
2. Triangle B → B': This looks like a reflection across a horizontal line
3. Triangle C → C': This appears to be a translation (slide) down and right
4. Triangle D → D': This looks like a rotation (appears to be 90° clockwise)

Row 2:
5. Triangle E → E': This appears to be a translation up
6. Triangle F → F': This looks like a reflection across a diagonal line
7. Triangle G → G': This appears to be a rotation (looks like 180°)
8. Triangle H → H': This looks like a translation down and left

Row 3:
9. Triangle I → I': This appears to be a reflection across a vertical line
10. Triangle J → J': This looks like a translation left
11. Triangle K → K': This appears to be a rotation (90° counterclockwise)
12. Triangle L → L': This looks like a reflection across a horizontal line

Row 4:
13. Triangle M → M': This appears to be a reflection across a diagonal line
14. Triangle N → N': This looks like a rotation (180°)
15. Triangle O → O': This appears to be a translation up and right
16. Triangle P → P': This looks like a reflection across a vertical line

Row 5:
17. Triangle Q → Q': This appears to be a rotation (90° clockwise)
18. Triangle R → R': This looks like a translation down
19. Triangle S → S': This appears to be a reflection across a horizontal line
20. Triangle T → T': This looks like a rotation (90° counterclockwise)

Wait, let me reconsider more carefully. I should look at the specific characteristics:

For transformations:
- Translation: Same orientation, just moved
- Reflection: Mirror image (flipped)
- Rotation: Turned around a point
- Dilation: Changed size (but all these appear same size)

Let me re-examine each one more carefully by looking at the vertex positions and orientations:

Actually, without being able to measure precisely, I'll identify based on visual patterns:

The worksheet asks students to "GUESS THIS! Transformation" - so they need to identify the type of transformation for each pair.

Based on careful analysis of the geometric relationships:
