State whether True or False.
All squares are trapeziums.

Answer

To determine whether the statement "All squares are trapeziums" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- A **square** is a quadrilateral with all sides equal and all angles equal to 90 degrees.
- A **trapezium** (or trapezoid in some regions) is defined as a quadrilateral with at least one pair of parallel sides.

2. **Analyze the Properties of a Square**:
- In a square, opposite sides are equal and parallel. Therefore, a square has two pairs of parallel sides.

3. **Check the Definition of a Trapezium**:
- Since a trapezium requires at least one pair of parallel sides, and a square has two pairs of parallel sides, it meets the criteria for being a trapezium.

4. **Conclusion**:
- Since all squares have the property of having parallel sides, we can conclude that all squares are indeed trapeziums.

Therefore, the statement "All squares are trapeziums" is **True**.
