Need help! If a polygon has six sides, then it is called a hexagon. Identify the contrapositive of the conditional statement. A If a polygon is not called a hexagon, then it does not have six sides. B If a polygon does not have six sides, then it is not called a hexagon. C If a polygon has six sides, then it is not called a hexagon. D If a polygon is called a hexagon, then it has six sides.

I say it's B

OpenStudy (unklerhaukus):

the contrapositive of \[P\implies Q\]is\[\neg Q\implies \neg P\]

OpenStudy (unklerhaukus):

option B is not the CONTRAPOSITIVE, option B is an INVERSION of the original statement; \(\neg P\implies\neg Q\)

Thanks

OpenStudy (unklerhaukus):

The original statement is the implication: If a polygon has six sides, then it is called a hexagon. i.e. If \(P\), then \(Q\)

Am going with C
