In mathematics especially in verifying certain statements regarding geometry, two column proofs are used. A two-column proof contains a table with a logical series
of statements and reasons that reach a conclusion. It is commonly present
in geometry. Two column proofs always have two columns: statements and reasons.
The other choices don’t fit in the definition of two column proof.
In science, the four ways to
incorporate proof into the research paper are:
1.
If the research you
are investigating has been with other research paper before.
2.
There is an
experimental proof that the evidence is true.
3.
The research
published belongs to a reliable source.
4.
There are citations
of the evidence that you are investigating
