Answer:
Yes, angles are supplementary if (and only if) their measures sum to 180°
Step-by-step explanation:
Well, let's look at the definition:
Supplementary angles are two angles whose measures sum to 180°
A biconditional statement is a conjunction of two implications. Like this:
1. If Two angles are supplementary then whose measures sum to 180º
(p→q)
2.If their measures sum to 180º then two angles are supplementary
(q→p)
3. Two angles are supplementary if and only if whose measures sum to 180º
(p↔q)
(p↔q)=(p→q)^(p→q)
-----
We can say that this Biconditional Statement (p↔q) the Hypothesis p and the Conclusion q is reversible because if we change the order of the operands to
q ↔p the Logical value remains the same as p↔q, i.e.
"If their measures sum to 180º then two angles are supplementary."
