Lines and Angles WordPress.com. 158 Chapter 3 Perpendicular and Parallel Lines Explaining Why Steps are Parallel In the diagram at the right, each step is parallel to the step immediately below it and the bottom step is parallel to the floor. Explain why the top step is parallel to the floor. SOLUTION You are given that k 1∞ k 2 and k 2∞ k 3. By transitivity of parallel lines, k 1∞ k 3., Holt McDougal Geometry. 3-3 Proving Lines Parallel. Use the Converse of the Corresponding Angles Postulate and the given information to show that ℓ|| m. Example 1B: Using the Converse of the Corresponding Angles Postulate m3 = (4x –80)°, m7 = (3x –50)°, x = 30. m3 = 4(30) –80 = 40 Substitute 30 for x..

Slopes of Parallel Lines. In a coordinate plane, 2 nonvertical lines are parallel iff they have the same slope. And, any 2 vertical lines are parallel. Slopes of Perpendicular Lines. In a coordinate plane, 2 nonvertical lines are perpendicular iff the products of their slopes is … Possible answer: If the lines are dragged farther apart or closer together, there is no change in the ∠ measures. Since the lines remain , the amount of “tilt” of the line remains the same, so the ∠ measures remain the same. 3-2 ANGLES FORMED BY PARALLEL LINES AND TRANSVERSALS, PAGES 155–161 CHECK IT OUT!
