The contrapositive of this statement would be: If a triangle is not isosceles, then it is not equilateral. (b) If a number is divisible by 9, then it is divisible by 3. The contrapositive of this statement would be: If a number is not divisible by 3, then it is not divisible by 9. Remember, in a contrapositive statement, both the hypothesis and the conclusion are negated. This technique is useful in logic and mathematics to prove statements indirectly.
