Is the statement "All squares are rhombuses" true or false?

1. True

2. False

3. Depends on the definition of rhombus

4. None of the above

The correct answer is: True

The statement "All squares are rhombuses" is indeed true. A square is a specific type of rhombus that has all four sides that are equal in length and also has four right angles. Therefore, every square meets the definition of a rhombus, which is a quadrilateral with all sides of equal length. While all squares are rhombuses, not all rhombuses are squares since rhombuses do not have to have right angles. This relationship establishes the truth of the statement provided. In contrast, the other options either suggest a falsehood or introduce ambiguity where none exists, as the definition of a rhombus is clear and universally accepted in geometry. Thus, the correct answer is that the statement is true.
