Question

I) If m perpendicular to I, n perpendicular to I and m # n, then m parallel to n.
(ii) A line perpendicular to one of two parallel lines is perpendicular to the other
Write 'True' or 'False' for the following statements.​

Answer 1

I. True, because if m is perpendicular to l and n is perpendicular to l and m ≠ n, then m || n.

II. True, because if a line is perpendicular to one of two parallel lines, then the line is perpendicular to the other line.
