Question

if diagonals are drawn ina triangle how many total triangles are there

Answer 1

In case diagonals attracted a triangle then 9triangles will frame, since there would be no corner to corner stepped back to it, and the diagonals to each contiguous vertex would lie over the adjoining sides, the quantity of diagonals from a solitary vertex is three less the quantity of sides, or n-3.

Answer 2

Triangle does not have any diagonals.

Diagonals are formed when the vertices of two non consecutive sides of a figure are joined.

But in triangle there is no such pair.

Also, there is a formula for calculating the number of diagonals in any geometric figure i.e.,

Number of diagonals = n(n-3)/2 where ‘n’ is the number of sides, the figure has

So if we put n=3 (in case of triangle) then, we get, Number of diagonals=0
