Which of the given statements is correct? Justify your answer/s with examples.

A ) A square and a parallelogram are quadrilaterals.

B ) Opposite sides of a square and a parallelogram are parallel.

C ) A trapezoid has one pair of parallel sides.

D ) All the above

Answer: A square is a parallelogram. The definition of a parallelogram is a quadrilateral with both pairs of opposite sides parallel*. *This shows that A) and B) are correct. A trapezoid has no parallel sides in British English so C) is incorrect. This automatically proves that D) is incorrect. **Conclusion, A) and B) are correct and C) and D) are incorrect.**

Question 1:

‘A square is a rhombus but a rhombus is not a square’.

Answer: I do not agree with this statement. A square has four sides that are equal in length and the inner angles are 90°, a rhombus has four sides that are equal in length but the inner angles are **not **90°. **Conclusion, a square is not a rhombus and a rhombus is not a square.**
