  • @hentiaNINJA dude wtf are searching in a video thats called "To construct a OCTAGON with ruler (straightedge) and compass ", what do you want to see entertainment? ITS A FUCKING OCTAGON!

  • @mikseris13 go back to minding your own fucking business 

  • @hentiaNINJA go back to kindergarten

  • fantibulous! Not really a word....but thank you for your demo to draw octagon! i had so much trouble before....now totally get it from this!!!! thank you your a legand!

    Love you tube for learning!!

  • If everybody thought like this drawing we would still be in the stone age

  • You take point A and B, the you make a right angle line creating a cross hair the same as in a rifle scope, then you measure between the right angle lines from radius to radius straight across to the intersection to find the centers and draw your additional lines. It's way easier than this drawing shows, you only need to know one formula ( 3,4,5 ) and you can go from here to the moon

  • This video had a more complex way to make an octagon than I had initially learned.. now I am confused.

  • this video helped me on my homework! THANK YOU!!!
