3-2 Angles Formed by Parallel Lines and Transversals Lesson Quiz State the theorem or postulate that is related to the measures of the angles in each pair. Then find the unknown angle measures. 1. m 1 = 120°, m 2 = (60x)° 2. m 2 = (75x –30)°, m 3 = (30x + 60)° Corr. s Post.; m 2 = 120°, m 3 = 120° Alt. Ext. s Thm.; m 2 = 120° Jul 03, 2019 · Angles On Parallel Lines Worksheets Morningknitscom 32 Angles And Parallel Lines Inknotebook Solved 5 2 Practice Angles And Parallel Lines In The Figu Create a pair of parallel lines cut by a transversal and investigate the relationships among the angles that are created. Students will use informal arguments to establish facts about the angles created when parallel lines are cut by a transversal.

Transversal. Definition. What does one look like? Be sure to label all lines. Teaching Points. How many angles did we just create by drawing a transversal? Just like how we learned about vertical angles, adjacent angles, and linear pairs in the previous section, a transversal creates 4 more angle relationships. They are … Angles and Parallel Lines Algebra and Angle Measures Algebra can be used to find unknown values in angles formed by a transversal and parallel lines. If m ∠ 1 = 3 x + 15, m ∠ 2 = 4 x ∠-5, and m ∠ 3 = 5 y, find the value of x and y. p q, so m ∠ 1 = = m ∠ 2 because they are corresponding angles. m∠ 1 = m ∠ 2 3x + 15 = 4 x y-5 3 x + 15 -3 x = 4 5 -3 x 15 = x-5 15 + 5 = ° x 5 + 5 20 =
