From each vertex, N-4 diagonals can be drawn, where N is the number of vertices. The total number of diagonals in a prism will be N(N-4)/2, where N is the number of vertices. For N=12 (a hexagonal prism) The total number of diagonals is 12*8/2=48 Answer:48
A triangle has no diagonals
Triangles have 0 diagonals.
None
A scalene triangle, like any other triangle, has zero diagonals. This is because a diagonal is drawn between two vertices that are not adjacent to each other. In a triangle, each vertex is adjacent to both others, so no diagonals exist.In general, for a polygon with n sides, for each vertex there are n-3 adjacent vertices (that is, all vertices excluding the vertex itself and its two neighbors). However, each diagonal is incident upon two vertices, so one must divide by 2. The number of diagonals is then n(n-3)/2. This does not depend upon the lengths of the sides of the polygon, only upon the number of sides.
The number of Diagonals in one vertex of a Triangle is 0 (zero)..
there is 2 diagonals in a triangle
The formula is: 0.5*(n2-3n) = number of diagonals when n is the number of sides of the polygon
There are two diagonals in a trapezoid.
A geometrical triangle has 3 sides but no diagonals.
It has 20 diagonals
14 diagonals
Total diagonals formula: 0.5*(n^2 -3n) whereas n is the number of sides of the polygon
a triangle has three diagonals as well as three sides
From each vertex, N-4 diagonals can be drawn, where N is the number of vertices. The total number of diagonals in a prism will be N(N-4)/2, where N is the number of vertices. For N=12 (a hexagonal prism) The total number of diagonals is 12*8/2=48 Answer:48
It has 0 volume diagonals and 6 face diagonals hence the total number of diagonals are 6
14
