Answer:
p is perpendicular to n. Proved.
Step-by-step explanation:
See the diagram attached.
Let us assume that mm' and nn' are two straight lines parallel to each other and pp' is a transversal.
It is given that pp' is perpendicular to mm' i.e. ∠po'm = 90°
Now, since mm'║nn' and pp' is a transversal, so, ∠pon = ∠po'm = 90° {Those are corresponding angles}
So, pp' is also perpendicular to nn'. {Proved}
