If two lines form congruent adjacent angles, then they are perpendicular. just create an account. 3.5 Perpendicular Postulate: If give a line and a point not on the line, then there exists exactly one line through the point that is perpendicular to the given line. This postulate means that only one parallel line will pass through the point Q, no more than two parallel lines can pass at the point Q. Postulate of lines cut by a transversal If two lines a and b are cut by a transversal line t and a pair of corresponding angles are congruent, then the … © copyright 2003-2021 Study.com. Theorems: 1. Many theorems have been discovered about parallel and perpendicular lines. There are several postulates and theorems related to the angles formed b y the transv ersal cutting two parallel lines: Get the unbiased info you need to find the right school. Theorem 7-M If two parallel lines are cut by a transversal that is perpendicular to one of the parallel lines… 2. If the exterior sides of two acute adjacent angles are perpendicular, then the angles are complementary. 3.2If two sides of two adjacent acute angles are perpendicular, then the angles are complementary.
