1o triangles
To calculate the number of triangles that can be formed by connecting the vertices of a 20-sided polygon, we can use the formula n(n-1)(n-2)/6, where n is the number of vertices. For a 20-sided polygon, n = 20, so the formula becomes 20(20-1)(20-2)/6 = 1140. Therefore, you can fit 1140 triangles within a 20-sided polygon.
8 triangles will fit inside a 10 sided decagon
You can have an infinite number of triangles in a polygon, it would really depend on the size of the triangles you are trying to fit in.If on the other hand you mean that triangles are made by joining the point of the polygon to make triangles then it's the number of sides minus two.-n(sides)-2
It depends on the size of the square and the sizes and shapes of the triangles.
