Part A: How is proof by contradiction different from a traditional proof? What assumption statement will begin proof by contradiction for the given conditional statement? (3 points) Part B: Prove the given conditional statement is true by contradiction. (3 points) Add Audio Add Video Question 8 (Essay Worth 6 points) (02.07 MC) Lines m and n are cut by a transversal, as shown in the figure. Line l is drawn from the upper left to lower right. Lines m and n are drawn from the upper right to the lower left. Line l intersects line m and lines n. Where line l intersects line m, the angles formed are listed from the top in clockwise order: angle 1, angle 2, angle 3, and angle 4. Where line l intersects line n, the angles formed are listed from the top in clockwise order: angle 5, angle 6, angle 7, and angle 8. Given line m is not parallel to line n, prove 4 is not congruent to 6 by contradiction.
