Options

A. 2
B. 3
C. 4
D. 5

Answer

To construct a unique parallelogram, we need to determine the minimum number of measurements required. Here’s a step-by-step solution:

### Step 1: Understanding the Properties of a Parallelogram
A parallelogram has the following properties:
- Opposite sides are equal in length.
- Opposite angles are equal.
- The sum of the interior angles is 360 degrees.

### Step 2: Identifying Required Measurements
To construct a unique parallelogram, we need to define its shape and size. The minimum measurements required are:
1. The lengths of two adjacent sides.
2. The angle between those two sides.

### Step 3: Conclusion on Measurements
Thus, to construct a unique parallelogram, we need:
- **2 adjacent sides** (let's call them AB and AD).
- **1 angle** (let's say angle DAB).

### Final Answer
The minimum number of measurements required to construct a unique parallelogram is **3**.
