Theorem: If two lines in the same plane are perpendicular to the same line, then the lines are parallel to each other. If two coplanar lines are perpendicular to the same line, then the two lines are (perpendicular, parallel, skew) to each other. Explain your answer. a segment that divides another segment in half and meets it at a right angle. 1. View proofs_parallel_perp_lines_key.pdf from MATH 102 at California State University, Fullerton. Similarly, the other theorems about angles formed when parallel lines are cut by a transversal have true converses. You will investigate the concept of proof and discover 1 and 5 13. statements that are accepted as true without prior proof in order to provide a starting point for deductive reasoning. In today’s lesson, we will see a step by step proof of the Perpendicular Transversal Theorem: if a line is perpendicular to 1 of 2 parallel lines, it’s also perpendicular to the other. If two lines are cut by a transversal so that (alternate interior, alternate exterior, corresponding) angles are congruent, then the lines are parallel. Also, does anyone know a good proof to show that any line perpendicular to a specific line CD will always result in the product of the slopes being -1?
