What is used to support the steps of a geometric proof?
a) evidence based on observation or experiment
b) measurement and observation of many cases
c) postulates, definitions, given statements, and proven theorems
d) steps in a geometric proof do not require support
what, never done a proof? (C)!
The correct answer is c) postulates, definitions, given statements, and proven theorems.
In a geometric proof, each step must be supported by previous statements and established mathematical facts. This support is typically provided by using postulates (basic assumptions), definitions (established meanings of geometric terms), given statements (previously established facts or givens in the proof), and proven theorems (previously established geometric truths). These components serve as the foundation for the logical reasoning and progression within the proof, ensuring that each step is accurate and valid.
