    Let P a poin outside the line XY; PO a line perpendicular from P to XY, and PZ another line drawn from P to XY. Prove that PZ is not perpendicular to XY.

    TuringTest already helped me to prove it(He did it actually) but the thing is that I can't understand the proof that is given in the book.

    It was proved that the angle P'ZP has not colineal sides. and then proved that angle OZP is half angle P'ZP.

    It proved that OZP is half of an angle that is not a 90º angle.

    I think I understand now but I'm still incapable of doing that kind of proofs by myself. =/

    It seems so excessive. I couldn't do the proof myself like this, you saw my way. I'm not so sure I care to do proofs like this frankly :P

    then I guess this is the kind of stuff you should be learning I'm not that rigorous myself good for you though ;)

    Actually I wanted to study Ecuclid's elements. But I started doing this book before. So I don't want to start again.
