Consider the pentagon ABCDE. By drawing diagonals from B, we get: 1. Triangle ABE 2. Triangle BDE 3. Triangle BCD -Ashwin Hendre
A diagonal is normally defined as a straight line joining a vertex of a polygon with any vertex other than an adjoining vertex (lines joining a vertex to an adjoining vertex would simply be a side of the polygon). Since a triangle has only got adjoining vertices, it has no diagonals. Since there are no diagonals, they cannot bisect one another.
An n-gon has n(n-3)/2 total diagonals. You can draw n-3 diagonals from each vertex ( n>3) ( A triangle doesn't really have a diagonal) An alternative way of seeing this: from any vertex, you can draw a diagonal to any other vertex except itself and the immediate neighbour on either side (the latter would be sides of the n-gon). This gives n-3 diagonals.
a triangle has three diagonals as well as three sides

The number of Diagonals in one vertex of a Triangle is 0 (zero)..
1 triangle is formed.
There are no 'diagonals' in a triangle. Each vertex is connected to both of the other vertices, by the sides.

There are 5 diagonals

yes * * * * * No. In a polygon (a plane shape with sides which are straight lines), a diagonal is a line from one vertex to another provided it is not already a side of the polygon. In a triangle, the only lines which can join two vertices are sides of the triangle. Therefore they are not diagonals: that is, a triangle (right angled or not) cannot have diagonals.
If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
a triangle has three diagonals as well as three sides
