  • Unfortunately I don't think high school students learn much geometry any more. It is a situation I hope to change.

  • Good vid. And no this wasnt in my geometry class at my highschool.

  • Reflection of a line?? Hmm... Like white holes and black holes in space. Lol

  • Man, I need to look up a proof of the Euler Line sometime. On the surface it doesn't look like it would be very complex, but of course math can be very deceptive. Isn't the proof of Fermat's Last Theorem ridiculously long?

  • Thanks for the help, you really got me out of a sticky situation with my homework. :D

  • Very good. Is this high school geometry?
