What is the number of diagonals we can draw from one vertex of a octagon?
5 diagonals
You cannot draw diagonals to the vertex itself as well as two adjacent vertices and hence you can draw 5 diagonals from the vertex.
What is the number of the diagonals we can draw from one vertex of a polygon with 11 sides?
55 diagonals
In an 11-sided polygon, total vertices are 11. Now, the 11 vertices can be joined with each other by 11C2 ways i.e. 55 ways. Now, there are 55 diagonals possible for an 11-sided polygon which includes its sides also….Solution:

Which expression can be used to find the number of diagonals of a polygon having n sides?
nC2 lines
An n sided polygon has n vertices. If we join every distinct pair of vertices we will get nC2 lines. These nC2 lines include the n sides of the polygon as well as its diagonals. So the number of diagonals is given by the expression nC2 – n.
How many diagonals we can draw from one vertex of a polygon of N sides?
The interior angles of a triangle always add up to 180 degrees. This can easily be proved by the congruence of alternate interior angles. From a given vertex of a polygon with n sides, (n-3) diagonals can be drawn.
How many diagonals can you draw from that vertex?
The number of diagonals in a polygon that can be drawn from any vertex in a polygon is three less than the number of sides. To find the total number of diagonals in a polygon, multiply the number of diagonals per vertex (n – 3) by the number of vertices, n, and divide by 2 (otherwise each diagonal is counted twice).
How many diagonals can you draw from one vertex of a decagon?
7
Answer: The number of diagonals that can be drawn from each vertex of a decagon is 7. Let’s look into the solution. Explanation: A decagon is a ten-sided polygon with ten vertices and ten angles.
What is the expression of number of diagonals in a polygon?
What is the formula for finding the number of diagonals in a polygon?
The number of diagonals of a polygon = n(n−3)/2 ‘n’ is the number of sides polygon has.
What is the formula for number of diagonals in a polygon?
How many diagonals can be drawn from each vertex of a 16 Gon?
Thus the set of diagonals is the larger set minus its complementary set, or n Choose 2, minus n. A hexadecagon has 16 sides, thus the number of diagonals will be 16 choose 2, minus 16 = 104.
