I'm taking a maths course this summer, and apparently my geometry is a lot worse than I thought. Can someone help me with this?
Draw a parallellogram ABCD. From A, draw the line AN perpendicular to CD and the line AM perpendicular to BC (N lies on the line CD, and M lies on the line BC). Show that MAN ~ ABC (not quite sure what this translates to, but that the triangles MAN and ABC are similar I think?)
Any help would be greatly appreciated, I'm feeling like an idiot here.
