Expert Answer
Since a polygon has 20 sides, total number of triangles can be drawn =
Using, one side of polygon, number of triangles that can be drawn = 16
Then, for 20 sides, number of triangles that can be drawn = 16 x 20 = 320

Using, two side of polygon, number of triangles that can be drawn = 20

Therefore, total number of triangles that can be drawn = 1140 - 320 - 20 = 800
