If a line is perpendicular is one of two given parallel lines;then it is also perpendicular to the other line.

If a line is perpendicular to one of the two given parallel lines then prove that it is also perpendicular to the other line.

Find the slope of a line perpendicular to the line 3x+5y=8 .

Two lines are respectively perpendicular to two parallel lines. Show that they are parallel to each other.

Which of the following statements are true (T) and which are false (F)? Give reasons. (i)If two lines are intersected by a transversal, then corresponding angles are equal. (ii)If two parallel lines are intersected by a transversal, then alternate interior angles are equal. (iii)Two lines perpendicular to the same line are perpendicular to each other. (iv)Two lines parallel to the same line are parallel to each other. (v)If two parallel lines are intersected by a transversal, then the interior angle on the same side of the transversal are equal.
