Inverses and Contrapositives

9.3.2.2 Accurately interpret and use words and phrases in geometric proofs such as "if…then," "if and only if," "all," and "not." Recognize the logical relationships between an "if…then" statement and its inverse, converse and contrapositive.

guiding question how do i negate conditional statements

Lesson Objective: Iwbat convert a conditional statement into its inverse and contrapositive.

  • Write the following as a conditional and then write the converse.
  • Two angles whose sum is 90 are complementary.
Guiding Question: How do I negate conditional statements?
guiding question how do i negate conditional statements1

The inverse and contrapositive of statement say the opposite of a statement.

  • Inverse – negate the conditional (if –p then –q)
  • Contrapositive – switch the conclusion and hypothesis of the inverse.
  • Conditional Statement

If 2 angles are vertical, then they are congruent.

  • What is the hypothesis?
  • What is the conclusion?
  • What is the inverse?
  • What is the contrapositive?
