If we turn of the water pthen the water will stop pouring q. In this case, the statement is true since the conditional premise is false. The negation is "There exists a red object that does not have color.

A conditional and its converse do not mean the same thing If we negate both the hypothesis and the conclusion we get a inverse statement: No it is not. A false conditional statement with a converse that is true All those who have four legs each are cows!

Similarly, take the statement "All quadrilaterals have four sides," or equivalently expressed "If a polygon is a quadrilateral, then it has four sides.

The converse is false. Therefore, in this case the inverse is false. Complete the truth table below. Example If we turn of the water in the shower, then the water will stop pouring. If today is Friday, then tomorrow is Tuesday. You could not disprove the theory by testing a wire made of aluminum!

The IF-Part is the hypotheses of the theory. Since the statement and the converse are both true, it is called a biconditionaland can be expressed as "A polygon is a quadrilateral if, and only if, it has four sides.

If the original statement reads "if j, then k", the inverse reads, "if not j, then not k. In each case, either the hypothesis and the conclusion switch places, or a statement is replaced by its negation. If a statement reads, "The vertex of an inscribed angle is on a circle", then the inverse of this statement is "The vertex of an angle that is not an inscribed angle is not on a circle.

The biconditional of p and q is "p if, and only if, q" and is denoted p q.Converse. Switching the hypothesis and conclusion of a conditional statement. For example, the converse of "If it is raining then the grass is wet" is "If the grass is wet then it is raining." As in the example, a proposition may be true but have a false converse.
