If in a quadrilateral, two adjacent sides are equal and the opposite sides are unequal, then it is called a

Options

A. parallelogram
B. square
C. rectangle
D. kite

Answer

To solve the question, we need to analyze the properties of the quadrilateral described in the problem.

### Step-by-Step Solution:

1. **Understanding the Given Information**:
We have a quadrilateral where two adjacent sides are equal, and the opposite sides are unequal. Let's denote the quadrilateral as ABCD, where AB = AD (the two adjacent sides).

2. **Identifying the Properties**:
In this quadrilateral:
- AB = AD (two adjacent sides are equal)
- BC ≠ CD (the opposite sides are unequal)

3. **Analyzing the Options**:
We need to determine which type of quadrilateral fits this description. The options are:
- Parallelogram
- Square
- Rectangle
- Kite

4. **Checking Each Option**:
- **Parallelogram**: In a parallelogram, opposite sides are equal. Since we have opposite sides that are unequal, it cannot be a parallelogram.
- **Square**: A square has all sides equal and opposite sides equal. Since we have unequal opposite sides, it cannot be a square.
- **Rectangle**: A rectangle also has opposite sides equal. Again, since we have unequal opposite sides, it cannot be a rectangle.
- **Kite**: A kite has two pairs of adjacent sides that are equal, and it does not require the opposite sides to be equal. This matches our description perfectly.

5. **Conclusion**:
Therefore, the quadrilateral described in the question is called a **kite**.
