Answer 1

@michelle01 any idea about this ? do you know the way how you can - need - prove a statement that is true or false ?

old question, answering to close

Which are correct statements regarding proofs? Select three options.

In a paragraph proof, statements and their justifications are written in sentences in a logical order. ---> true. like the name suggests, paragraph proofs are made up of sentences that explains each step of the proof and why it's true.

A two-column proof consists of a list statements and the reasons the statements are true. ---> true, as this how two column proofs are set up. statements are on the left, reasons/justifications are on the right.

A flowchart proof gives a visual representation of the sequence of steps without justifications. ---> false, as you still need to justify each step on a flowchart proof

A flowchart proof is a visual way of describing the statements and reasons for a proof. ---> true, as a flowchart is simply a way to visualize each step (see above)

A two-column proof lists only the given information and what is to be proven. --> false, as we stated earlier, you need statements and justifications for a two-column proof
