To solve the problem of identifying which fingerprints are matches, we need to carefully compare the patterns and features of each fingerprint. Fingerprints are unique to individuals, but prints from the same finger will share similar ridge patterns, core structures, and minutiae (small details like ridge endings or bifurcations).
Step-by-Step Solution:
1.
Understand the Task:
- We need to identify which fingerprints are made by the same finger.
- Some fingerprints may appear more than once.
2.
Key Features to Compare:
-
Ridge Patterns: The overall flow and arrangement of ridges.
-
Core Structure: The central part of the fingerprint where the ridges form a specific pattern (e.g., loop, whorl, arch).
-
Minutiae: Small details such as ridge endings, bifurcations, and dots.
3.
Comparison Process:
- Carefully examine each fingerprint and compare it with all others.
- Look for similarities in the core structure and ridge patterns.
- Pay close attention to minutiae that are consistent across multiple prints.
4.
Grouping Matches:
- After comparing, group fingerprints that have identical or very similar patterns.
Analysis of the Fingerprints:
#### Group 1: Loops
-
Fingerprints A, F, K, P:
- These all have a
loop pattern with a single core.
- The ridge patterns and core structures are very similar.
- Minutiae (ridge endings and bifurcations) align closely.
#### Group 2: Whorls
-
Fingerprints B, G, L, Q:
- These all have a
whorl pattern with two cores.
- The ridge patterns and core structures are consistent.
- Minutiae match well across these prints.
#### Group 3: Arches
-
Fingerprints C, H, M, R:
- These all have an
arch pattern with no core.
- The ridge patterns are simple and consistent.
- Minutiae are minimal but match across these prints.
#### Group 4: Compound Patterns
-
Fingerprints D, I, N, S:
- These have a
compound pattern (a mix of loop and whorl characteristics).
- The ridge patterns and core structures are similar.
- Minutiae align closely.
#### Group 5: Unique Patterns
-
Fingerprints E, J, O, T:
- These have distinct patterns that do not match any other group.
- Each appears to be unique.
Final Matching Groups:
1.
Group 1 (Loops): A, F, K, P
2.
Group 2 (Whorls): B, G, L, Q
3.
Group 3 (Arches): C, H, M, R
4.
Group 4 (Compound Patterns): D, I, N, S
5.
Unique Patterns: E, J, O, T
Conclusion:
The fingerprints that are matches are grouped as follows:
-
A, F, K, P
-
B, G, L, Q
-
C, H, M, R
-
D, I, N, S
Thus, the final answer is:
\[
\boxed{A-F-K-P, B-G-L-Q, C-H-M-R, D-I-N-S}
\]
