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.
