 Outside across from the word: › write the symbol for conditional: p -> q  INSIDE: › How to write the statement : If p, then q. › Example : If an angle is a right angle, then its measure is 90 degrees.

 Outside across from the word: › write the symbol for converse: q -> p  INSIDE: › How to write the statement : If q, then p. › Example : If the measure of an angle is 90 degrees, then the angle is a right angle.

 Outside across from the word: › write the symbol for inverse: ~p -> ~q  INSIDE: › How to write the statement : If not p, then not q. › Example : If an angle is not a right angle, then its measure is not 90 degrees.

 Outside across from the word: › write the symbol for contrapositive: ~q -> ~p  INSIDE: › How to write the statement : If not q, then not p. › Example : If the measure of an angle is not 90 degrees, then the angle is not a right angle.

 Outside across from the word: › write the symbol for biconditional: p q  INSIDE: › How to write the statement : p if and only if q. › Example : An angle is a right angle if and only if its measure is 90 degrees.
