Number of sides - 2
The number of Diagonals in one vertex of a Triangle is 0 (zero)..
If you mean "How many diagonals can be drawn from one vertex of a figure with 16 sides", the formula is n-3, where "n" being the number of sides of the figure. So 16-3 = 13 diagonals that can be drawn from one vertex.

The number of Diagonals in one vertex of a Triangle is 0 (zero)..
The formula for the number of diagonals is: 0.5*(n^2-3n) whereas 'n' is the number of sides of the polygon
In a polygon with n sides, the number of diagonals that can be drawn from one vertex is given by the formula (n-3). Therefore, in a 35-sided polygon, you can draw (35-3) = 32 diagonals from one vertex.
Number of sides minus two equals number of diagonals drawn from one vertex.
You can use the formula D=S-2 where D is the number of possible diagonals and S is the number of sides the polygon has.

how many diagonals from a vertex a heptagon have
The number of diagonals per vertices can be found by taking n(number of sides) minus 3, or n-3. Thus a pentagonal prism will have 5 sides per base, making the formula 5-3=2. There are 2 diagonals per vertex in a pentagonal prism. Source: My math teacher

47 sides. Take a vertex of an n-sided polygon. There are n-1 other vertices. It is already joined to its 2 neighbours, leaving n-3 other vertices not connected to it. Thus n-3 diagonals can be drawn in from each vertex. For n=50, n-3 = 50-3 = 47 diagonals can be drawn from each vertex. The total number of diagonals in an n-sided polygon would imply n-3 diagonals from each of the n vertices giving n(n-3). However, the diagonal from vertex A to C would be counted twice, once for vertex A and again for vertex C, thus there are half this number of diagonals, namely: number of diagonals in an n-sided polygon = n(n-3)/2.
Using the formula 0.5(n^2 -3n) whereas n is number of sides, altogether there are 104 diagonals in a 16 sided polygon
