Can you show me the formula Kevin?

Thanks Kevin!

kevin · Answer

wait

v-sync · Answer

Whats up Kevin?

kevin · Answer

It's hexagon. Hexagon has 4 triangles in it. That's mean angle sum is 4*(180) = 720
135+62+151+140+n+(n+6)=720
n = 113 degree

kevin · Answer

You know 4 triangles :

|dw:1474484287870:dw|

v-sync · Answer

How do you know how many triangles are in each shape?

kevin · Answer

Look my drawing above

v-sync · Answer

I mean like in pentagons or octagons or a different shape, how do you know how many triangles are there?

kevin · Answer

You can draw it.. I mean using the same way as I draw triangles in hexagon

kevin · Answer

Or the quick way is using formula :
number of triangles = number of vertices - 2

kevin · Answer

ok? :)
