How many triangles are there within a nonagon?

Answer 1

if you need to know how many triangles are in a polygon ... just take the number of its sides and subtract for example.

nonagon has 9 sides so it will be 9-2=7

so, a nonagon has 7 triangles

Answer 2

to calculate the number of possible triangles within a nonagon, one must use combinatorics. Understand that at first you have to pick the first vertex from 9 points, then the second from eight other possible points, and the third from 7 possible points. And finally that by this process any three vertices could be picked in 6 different orders. triangles possible are: 9*8*7/6 = 84 possible triangles in a nonagon
