Question

What does this supposed to mean......
- In a dictionary, find the definitions of three words. Write them down verbatim, and be sure to cite your source.
Rewrite the definitions so that they are written as biconditionals. Recall that a biconditional is written in the form “A if and only if B

Answer 1

Any ideas?

Answer 2

The converse of a statement in " if-then" form is obtained by

interchanging the "if" and "then" parts of the statement.

Answer 3

Find three definitions in the dictionary and write them in "if-then" form:

If A, then B.

$$\huge A \Rightarrow B$$

Then interchange the "if" and "then" parts of the statement:

(This is called the "converse" of the above statement.)

If B then A.

$$\huge B \Rightarrow A$$

Rewrite the definitions so that they are written as biconditionals.

Recall that a biconditional is written in the form “A if and only if B"

$$\huge A \iff B$$
