i don't know that is why i asked you
To determine the number of triangles that can be formed within a 13-sided polygon, we can use the formula nC3, where n is the number of vertices in the polygon. In this case, n = 13. So, 13C3 = 286 triangles can be formed within a 13-sided polygon.
Well, honey, a 19-sided polygon can have a maximum of 646 triangles. But let's be real, counting all those triangles is about as fun as watching paint dry. Just trust me on this one, there are 646 triangles in that bad boy.
21
it should make a square leaned over
It has 23 triangles
18 triangles
Two triangles can be formed by the diagonals of one vertex of a four-sided polygon.
The number of triangles formed by the diagonals of a 21 sided polygon is C(21,3) = 21x20x19/3x2x1 = 1,330.
13 triangles will be formed
In a polygon with n sides, the sum of the interior angles is given by (n-2) * 180 degrees. Each triangle has interior angle sum of 180 degrees. Therefore, the number of triangles that can be formed in a polygon is equal to (n-2) * 180 / 180, which simplifies to (n-2). In other words, the number of triangles is two less than the number of sides in the polygon.
To determine the number of triangles that can be formed within a 13-sided polygon, we can use the formula nC3, where n is the number of vertices in the polygon. In this case, n = 13. So, 13C3 = 286 triangles can be formed within a 13-sided polygon.
The number of triangles that can be formed within a regular polygon depends on the number of sides the polygon has. For an n-sided polygon, where n is greater than or equal to 3, you can form n-2 triangles within the polygon. This is because each triangle is formed by connecting one vertex to any other two non-adjacent vertices. So, for example, in a regular pentagon (5-sided polygon), you can form 5-2 = 3 triangles.

A pyramid
It is: 8-2 = 6 triangles
Well, honey, a 19-sided polygon can have a maximum of 646 triangles. But let's be real, counting all those triangles is about as fun as watching paint dry. Just trust me on this one, there are 646 triangles in that bad boy.
