Imagine drawing a diagonal from one of the vertices to all of the other vertices. Two of these lines would be the outer edge so we don't count those. We have just drawn 13 diagonals. Move to the next corner and draw again. Don't

count the outer two and don't re-count the one to the previous corner so we have 12. Each corner goes down by one so the answer is 13+ 12+ 11+...+ 3+ 2+ 1= 91.

How many diagonal can be drawn from a regular hexagon from one vertex?

5 diagonals * * * * * That is not correct since two of these would be lines joining the vertex to adjacent vertices (one on either side). These are sides of the polygon, not diagonals. The number of diagonals from any vertex of a polygon with n sides is n-3.

If in a 54 sided polygon all possible diagonals are drawn from one vertex they divide the interior of the polygon into how many regions?

In a 54-sided polygon, 53 possible diagonals can be drawn from one vertex to another. These diagonals will not intersect. Therefore, the interior will be divided into 54 regions by the 53 diagonals plus the two sides of the original polygon that adjoin the vertex from which the diagonals are drawn.
