3 3 Practice Proving Lines Parallel Form K Answers. Web study with quizlet and memorize flashcards containing terms like lines a and b are parallel and lines e and f are parallel. If two lines in a plane are cut by a transversal so that a pair of consecutive interior angles is supplementary, then the lines are parallel.
Complete the flow proof below. W // z and x // y. Complete the flow proof below. Web the diagram below shows two parallel lines {eq}k {/eq} and {eq}j {/eq} and a transversal {eq}w {/eq}, determine the missing statement in the proof. If a and b are complementary, then m a + m b =90°. Web angle relationships with parallel lines. If two lines in a plane are cut by a transversal so that a pair of consecutive interior angles is supplementary, then the lines are parallel. We know that if they are parallel,. Lines a and b are parallel because their alternate exterior angles are congruent. If a = b, then a + c = if a + c = b + c, then b + c. Web w // x and y // z.
