Example 6 Write the component statements of the following compound statements and check whether the compound statement is true or false. (i)A line is straight and extends indefinitely in both directions. The component statements are p: A line is straight. q: A line extends indefinitely in both directions. We know that p is true , q is true. Both statement are true. The connecting word is and Hence the compound statement is true.
