As an experienced tutor registered on UrbanPro, I'm here to help you understand the contrapositive of the given if-then statements.
(a) If a triangle is equilateral, then it is isosceles.
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. If you have any further questions or need clarification, feel free to ask!
