Fingerprint Matching Worksheet Answers - Fill Online, Printable ... - Free Printable

The task in the image involves fingerprint matching, where you need to use deductive reasoning to determine which handprints were made by which object. Here's how to approach and solve this problem:

---

Step 1: Understand the Objective

You are given a set of objects (A–L) and a set of handprints. Your goal is to match each handprint to the object that caused it. The key is to observe the unique characteristics of each handprint and relate them to the physical properties of the objects.

Step 2: Analyze the Objects

Each object has distinct physical features that will leave unique marks on the handprints:
- A. Light switch: Likely leaves a rectangular or square mark.
- B. Standard doorknob: Leaves a circular or oval mark.
- C. Baseball: Leaves a circular mark with a textured pattern.
- D. Bottle: Leaves a cylindrical mark.
- E. Pencil Sharpener: Likely leaves a small, sharp-edged mark.
- F. Electric plug: Leaves a rectangular or triangular mark.
- G. Computer mouse: Leaves an irregular, elongated mark.
- H. ChapStick: Leaves a small, smooth, circular mark.
- I. Dumbbells: Leaves a heavy, possibly distorted mark.
- J. Hair brush: Leaves a comb-like pattern.
- K. Locker: Leaves a rectangular or square mark.
- L. Drumstick: Leaves a long, thin, cylindrical mark.

Step 3: Analyze the Handprints

Carefully examine each handprint for distinctive features such as shape, size, texture, and pattern. Match these features to the corresponding object.

#### Handprint Analysis:
1. Handprint 1: This print shows a rectangular or square shape. It likely corresponds to an object with a flat, rectangular surface.
- Match: A. Light switch or K. Locker.

2. Handprint 2: This print shows a circular or oval shape with a smooth edge.
- Match: B. Standard doorknob.

3. Handprint 3: This print shows a circular shape with a textured pattern.
- Match: C. Baseball.

4. Handprint 4: This print shows a cylindrical shape.
- Match: D. Bottle.

5. Handprint 5: This print shows a small, sharp-edged mark.
- Match: E. Pencil Sharpener.

6. Handprint 6: This print shows a rectangular or triangular shape.
- Match: F. Electric plug.

7. Handprint 7: This print shows an irregular, elongated shape.
- Match: G. Computer mouse.

8. Handprint 8: This print shows a small, smooth, circular mark.
- Match: H. ChapStick.

9. Handprint 9: This print shows a heavy, distorted mark.
- Match: I. Dumbbells.

10. Handprint 10: This print shows a comb-like pattern.
- Match: J. Hair brush.

11. Handprint 11: This print shows a rectangular or square shape.
- Match: K. Locker (already matched to Handprint 1).

12. Handprint 12: This print shows a long, thin, cylindrical shape.
- Match: L. Drumstick.

Step 4: Final Matching

Based on the analysis, the final matches are:
1. Handprint 1: K. Locker
2. Handprint 2: B. Standard doorknob
3. Handprint 3: C. Baseball
4. Handprint 4: D. Bottle
5. Handprint 5: E. Pencil Sharpener
6. Handprint 6: F. Electric plug
7. Handprint 7: G. Computer mouse
8. Handprint 8: H. ChapStick
9. Handprint 9: I. Dumbbells
10. Handprint 10: J. Hair brush
11. Handprint 11: A. Light switch
12. Handprint 12: L. Drumstick

Final Answer:

\[
\boxed{
\begin{array}{ll}
\text{Handprint 1} & \text{K. Locker} \\
\text{Handprint 2} & \text{B. Standard doorknob} \\
\text{Handprint 3} & \text{C. Baseball} \\
\text{Handprint 4} & \text{D. Bottle} \\
\text{Handprint 5} & \text{E. Pencil Sharpener} \\
\text{Handprint 6} & \text{F. Electric plug} \\
\text{Handprint 7} & \text{G. Computer mouse} \\
\text{Handprint 8} & \text{H. ChapStick} \\
\text{Handprint 9} & \text{I. Dumbbells} \\
\text{Handprint 10} & \text{J. Hair brush} \\
\text{Handprint 11} & \text{A. Light switch} \\
\text{Handprint 12} & \text{L. Drumstick} \\
\end{array}
}
\]

This solution uses deductive reasoning by carefully observing the unique characteristics of each handprint and relating them to the physical properties of the objects.
