Which of the following statements are true and which are false ?
Every square is a parallelogram.

Answer

To determine whether the statement "Every square is a parallelogram" is true or false, we can analyze the properties of both shapes step by step.

### Step 1: Define a Parallelogram
A parallelogram is a quadrilateral with the following properties:
- Opposite sides are equal in length.
- Opposite angles are equal.
- The diagonals bisect each other.

### Step 2: Define a Square
A square is a special type of quadrilateral that has the following properties:
- All four sides are equal in length.
- All four angles are equal (each measuring 90 degrees).
- The diagonals are equal in length and bisect each other at right angles.

### Step 3: Compare Properties
1. **Opposite Sides**:
- In a parallelogram, opposite sides are equal.
- In a square, since all sides are equal, opposite sides are also equal.
- **Conclusion**: This property holds true for both shapes.

2. **Opposite Angles**:
- In a parallelogram, opposite angles are equal.
- In a square, all angles are equal (90 degrees), hence opposite angles are also equal.
- **Conclusion**: This property holds true for both shapes.

3. **Diagonals**:
- In a parallelogram, the diagonals bisect each other.
- In a square, the diagonals also bisect each other and are equal in length.
- **Conclusion**: This property holds true for both shapes.

### Step 4: Conclusion
Since all properties of a parallelogram are satisfied by a square, we can conclude that:
- **Statement**: "Every square is a parallelogram" is **True**.

### Final Answer
True, every square is a parallelogram.
