Example 5 Find the component statements of the following and check whether they are true or not. (i) A square is a quadrilateral and its four sides equal. The component statements are p: A square is quadrilateral. q: A square has all its sides equal. The connecting word is And . We know that a square is quadrilateral Hence p is true We know that square has all its equal Hence q is true Hence both component statement are true Example: 2 is prime but not odd Hence q is false. Hence ,both the components statement are false.
