Determine the antecedent and consequent of the following implication :

If k = −4, then k³ = −64.

• Antecedent : k ≠ −4

  Consequent : k³ ≠ −64

• Antecedent : k ≠ −64

  Consequent : k³ ≠ −4

• Antecedent : k = −64

  Consequent : k³ = −4

• Antecedent : k = −4

  Consequent : k³ = −64

• If a polygon is not a trapezoid, then it is not a quadrilateral.

• If a polygon is a trapezoid, then it is a quadrilateral.

• A rectangle is also a quadrilateral.

Refer to the following statement: "If a polygon is a quadrilateral, then it is a trapezoid."

What is the inverse of this statement?

• If the polygon is not a quadrilateral, then it is not a trapezoid.

• If the polygon is not a trapezoid, then it is not a quadrilateral.
