Its evident that in the truth table of $p \to q$
When $p$ is False and $q$ is True, Then $p \to q$ is True.
But in some instances i could not convince myself about this truth value.
For example:
$p$: Quadrilateral is Cyclic
$q$: Opposite angles are supplementary
Now is $p$ is False and $q$ is True, how can $p \to q$ can be True?
