Write and apply proofs about parallel and perpendicular lines. Start studying HCHS Geometry Unit 1B C2-C3 Proofs involving Angles and Parallel Lines. A is not in plane Q, then A is not on BD . 1. We know that if we have two lines that are parallel-- so let me draw those two parallel lines, l and m. So that's line l and line m. We know that if they are parallel, then if we were to draw a transversal that intersects both of them, that the corresponding angles are equal. I can do so many different activities. View proofs_parallel_perp_lines_key.pdf from MATH 102 at California State University, Fullerton. m, rn2 In a coordinate plane, two non-vertical lines are perpendicular if and only if the product of their slopes is Negative reciprocals Find an equation of the line parallel to y = - -x + 2 passing through (8, -3). Perpendicular line proofs. You will extend your knowledge of the characteristics of angles and parallel and perpendicular lines and explore practical applications involving angles and lines. If plane P and plane Q intersect, then they intersect in a line. 3. Any two vertical lines are parallel. In this lesson we will focus on some theorems abo… Practice this topic.
