Non Consecutive Vertices

Non consecutive vertices mean the vertices which are not in the adjacent. Here we are going to learn about the non consecutive vertices of the planes. Generally we can say opposite vertices of the polygons are called non consecutive vertices. We will see some examples for non consecutive vertices. This will help us to understand the non consecutive vertices.  Basically a vertex in a polygon refers the intersection point of two sides.

Non Consecutive Vertices:

Basically non consecutive vertices of a polygon mean the vertex which does not lies next to the other. In other words we can say the opposite vertices or the other vertices which is not lies very next to the vertex. The distance between the two vertices will give us the height or width of the polygon. If we find the distance we can calculate the area and volume of the polygon.

If we are having a polygon with n number of vertices then each polygons vertex is having n – 3 non consecutive vertices. For example if we take a square it is having 4 sides. So for each vertex it has n – 3 = 4 – 3 = 1 non consecutive vertices. We can calculate the diagonals of the square using the non consecutive vertices.

Examples for Non Consecutive Vertices:


Example 1 for non consecutive vertices:

Find the number of non consecutive vertices in the following polygon.

non consecutive vertices - 1

Solution:

In the above diagram we are having the number of sides as 6.

We know for a single vertex we have n – 3 numbers of vertices.

So for a six vertices we have 6 (n – 3) vertices = 6 (6 – 3) = 6 x 3 =18 non consecutive vertices.


Example 2 for non consecutive vertices:

Find the number of non consecutive vertices in the following polygon.

non consecutive vertices - 2

Solution:

In the above diagram we are having the number of sides as 8.

We know for a single vertex we have n – 3 numbers of vertices.

So for a six vertices we have 8 (n – 3) vertices = 8 (8 – 3) = 8 x 5 =40 non consecutive vertices.
