ehidna [41]

A conditional is an if-then statement.  The part after "if" is called the hypothesis; the part after "then" is called the conclusion.

We know that triangles have 3 sides.  We will start out with "if a figure is a triangle"; we end with "then it has three sides."

This is a true conditional statement.</span>
