The total number of subareas created by all the allowed diagonals (D=20) is thus A=8 x 10=80. Looking at the first few even sided polygons, the numbers of crossings C found for each sub-isosceles triangle, and the total sub-areas created divided by N, we find the following table-
WebApr 13, 2009 · A 5-sided polygon, 5. 6-sided, 9. By induction, an n-sided polygon has 'n*(n-3)/2' diagonals. "n" is how many sides a shape has. so, (7)*(7-3)/2 now we have, 7*4/2 so, 28/2 = 14 Therefore, a 7-sided polygon would have 14 diagonals.
WebMay 22, 2024 · Explanation: The number of diagonals of an n-sided polygon is: n(n − 3) 2 It is very immediate to understand: from any vertex, you can draw diagonals to every other vertex, except three: the vertex itself, and the one immediately before and after. So, for each of the n vertices you have n − 3 choices, for a total of n(n −3) WebSolution The correct option is A 6 The general expression for finding the number of diagonals drawn from one vertex of a n-sided polygon is n−3. ∴ the number of diagonals …
