Jordan has to prove the theorem that states: If two lines are cut by a transversal so that consecutive interior angles are supplementary, then the lines are parallel. She decides to solve it by indirect proof using the diagram below. 1/2 3/4 5. m + Which sentence should be Jordan's first statement? O A. Assume thatZ4 andZ5 are not congruent. O B. Assume thatZ1 andZ3 are not supplementary. Assume that Line r is not parallel to Line m. O D Assume that Angles 1 and 2 are not consecutive.
