  • @Thesmileyface231 basically you take his technique of dividing the shape up into triangles and work out the interior angles. Then you extend the sides and find the rest of the 180 angle made up of the interior angle you've found the side of and the exterior angle you're looking for. :)

  • Thank you very much, you are a good teacher and you have helped me a lot x

  • does any1 know where to find an video that shows how to find exterior angle measurements but the polygon IS NOT A REGULAR POLYGON? meaning that the sides are different? thx

  • too bad my exterior angles are written out with variables.

  • He reminds me of Josh Hutcherson...be my teacher? hahaha

  • you should include the dot dot dot or else it would be wrong
