Contradiction Method. The second or right column has only reasons supporting the validity of those mathematical statements, like "Given," or "If the opposite sides in a quadrilateral are the same length, then the figure is a parallelogram." The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles and the value is greater than either non-adjacent interior angle. Another one from the bag of tricks, all the ideas in the if clause appears in the statement column somewhere above the line youre checking. Perceiving what objects/ images mean/ signify is a major part of the work in this area of study. Another way of stating this definition is that a conclusion reached through the process of deduction is necessarily true if the premises are true. 6. Steps may be skipped.
