Athesis and proposition are synonymous.

True.

Explanation:

A thesis could be synonymous to a proposition as both of them imply an act of offering an idea or thought before the readers or listener. However, the form of both the words vary as proposition is the verbal act of offering while a thesis is the statement that proposes the central argument of an essay or research paper. Yet more often a proposition is considered as a thesis as it defines an argument in a situation or context. Thus, we may conclude both of them could be considered synonymous.
