12. Write the statement as a bicondtional.
A If point R is not between points P and Q on a line, then PR+RQ does not equal PQ
B If PR+RQ=PQ, then Point R is between points P and Q on a line.
C If PR +RQ does not = PQ, then point R is not between points P and Q on a line.
D Point R is between points P and Q on a line, if and only if PR+RQ=PQ
13. Is the biconditional statement true?
A True
B False
