A geometric representation showing the relationship between a whole and its parts is a

Options

A. Pie chart
B. Histogram
C. Bar graph
D. Pictograph

Answer

To solve the question, we need to identify which of the given options represents the relationship between a whole and its parts geometrically.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a geometric representation that shows the relationship between a whole and its parts. This means we are looking for a visual tool that divides a whole into different sections representing parts of that whole.

2. **Analyze the Options**:
- **Option A: Pie Chart**: A pie chart is a circular chart divided into slices to illustrate numerical proportions. Each slice represents a category's contribution to the whole.
- **Option B: Histogram**: A histogram is a graphical representation of the distribution of numerical data, typically used for showing frequency distributions. It does not show parts of a whole.
- **Option C: Bar Graph**: A bar graph represents categorical data with rectangular bars. It shows comparisons between categories but does not depict parts of a whole.
- **Option D: Pictograph**: A pictograph uses pictures or symbols to represent data. While it can show quantities, it does not specifically represent parts of a whole.

3. **Identify the Correct Option**: Among the options, the pie chart (Option A) is the only one that visually represents the relationship between a whole and its parts. Each slice of the pie chart corresponds to a part of the whole, making it the correct answer.

4. **Conclusion**: Therefore, the answer to the question is:
- **A pie chart**.

### Final Answer:
A geometric representation showing the relationship between a whole and its parts is a **Pie Chart**.
