a combination of a conditional and its converse when both are true.
What is a Biconditional Statement?
300
A proof argument for a conditional is a sequence of justified conclusions, start with the antecedent and ending with the consequent

Conjectures, conditional statements and logical arguments are all important for determining information needed from information already given in geometry.
Why are conjectures, conditional statements, and logical arguments are important to geometry?
