Question

True or false? If you took a true "if-then" statement and reversed the clauses, the new statement would also be true

Answer 1

That's false.

Here's a counter-example:

If an animal is a dog, then it has four legs.  This is true.
but
If an animal has four legs, then it is a dog.  This is not necessarily true.


Another one:

If a shape is a square, then it has four sides.  Always true.
but
If a shape has four sides, then it is a square.  Usually not true.
