Question

prove that if a line is perpendicular to x of two Parallel Lines then it is perpendicular to the order line also​

Answer 1

The linear pair perpendicular theorem states that when two straight lines intersect at a point and form a linear pair of equal angles, they are perpendicular. A linear pair of angles is such that the sum of angles is 180 degrees. As the angles measure 90 degrees, the lines are proved to be perpendicular to each other.
