Given statement: If two angles add to 180°, then they are supplementary. converse If two angles are not supplementary, then they do not add to 180°. inverse If two angles are supplementary, then they add to 180°. contrapositive If two angles do not add to 180°, then they are not supplementary.

Answer and Explanation:

We assume the things which are as follows

Statement = when p, so q

Converse = when q, so p

Inverse = when no p, so no q

Contrapositive = when it's not q so NOT P.

Now

Statement:

If we add two angles to 180°, then we called supplementary

Converse:

And, if the two angles are supplementary so their sum equal to 180°

Inverse:

Now if the sum of two angles is not 180° so we do not called as supplementary

Contrapositive:

And, if the two angles are not supplementary so their sum is not equal to 180°
