Test each statement below to see if it is reversible. If it it is, write it as a true biconditional. If not, write not reversible.
1. If a whole number is a multiple of 2, then the whole number is even
2. Rabbits are animals that eat carrots.
3.two lines that intersect to form four 90 degree angles are perpendicular
4. Mammals are warm-blooded animals.
1. Reversible and true biconditional: A whole number is a multiple of 2 if and only if the whole number is even.
2. Reversible: Animals that eat carrots are rabbits.
3. Not reversible: Two lines that intersect to form four 90 degree angles are perpendicular.
4. Reversible and true biconditional: Mammals are warm-blooded animals if and only if mammals are warm-blooded animals.
1. If a whole number is a multiple of 2, then the whole number is even: True biconditional | A whole number is even if and only if it is a multiple of 2.
2. Rabbits are animals that eat carrots: Not reversible | It is possible for animals other than rabbits to eat carrots.
3. Two lines that intersect to form four 90-degree angles are perpendicular: True biconditional | Two lines are perpendicular if and only if they intersect to form four 90-degree angles.
4. Mammals are warm-blooded animals: Not reversible | There are animals that are warm-blooded but not mammals, such as birds.
