Give reasons for the following :
A rectangle can be thought of as a special parallelogram.

Answer

To explain why a rectangle can be thought of as a special type of parallelogram, we can break down the reasoning into several steps:

### Step-by-Step Solution:

1. **Definition of Parallelogram**: A parallelogram is a quadrilateral (four-sided figure) where opposite sides are both parallel and equal in length.

2. **Properties of a Rectangle**: A rectangle is also a quadrilateral, and it has specific properties:
- Opposite sides are parallel and equal in length.
- All interior angles are equal and measure 90 degrees.

3. **Comparison of Properties**:
- Since a rectangle has opposite sides that are parallel and equal, it satisfies the first condition of being a parallelogram.
- Additionally, the fact that all angles in a rectangle are right angles (90 degrees) is a special characteristic that distinguishes rectangles from other types of parallelograms.

4. **Conclusion**: Because a rectangle meets all the criteria of a parallelogram and has the additional property of having all right angles, we can conclude that a rectangle is a special type of parallelogram.

### Final Statement:
Thus, we can say that a rectangle can be thought of as a special parallelogram because it has all the properties of a parallelogram, with the added feature of having right angles.
