2. Two angles are congrent if and only if their measures are equal.
3 .A solution is a base if the pH is greater than 7

Answer 1

Answer:

Explanation:

A biconditional statement is a combination of a conditional statement and its converse written in the  if and only if   form.

Two line segments are congruent if and only if  they are of equal length.

It is a combination of two conditional statements, “if two line segments are congruent then they are of equal length” and “if two line segments are of equal length then they are congruent”.

A biconditional is true if and only if both the conditionals are true.

Bi-conditionals are represented by the symbol ↔ or ⇔ .

p↔q means that p→q and q→p . That is, p↔q=(p→q)∧(q→p) .
