It is number of sides minus 2
One star has five triangles on the sides, and about three in the middle, if enough lines are drawn.
An infinite number. Having drawn a triangle, it can be converted into two triangles by simply adding a line from any vertex to any point on the opposite side. That increases the number of triangles by one. Repeat with another triangle. And again ...
110.Improved Answer:-It is 4
An n-gon has n sides.Incidentally, it is not called a n-agon.
There are 15 triangles in a 17-agon
18 triangles can be found in a 20-agon
It is number of sides minus 2
how many triangles are formed when any parallelogram and it diagonals are drawn
If all of the diagonals are drawn from a vertex of an octagon, how many triangles are formed
5 triangles are formed.
There are 16 possible triangles.
A ten-sided geometric figure could have ten triangles drawn inside it, if you connect the vertexes. 8 triangles
The least number of obtuse triangles, if all possible triangles are drawn for n points in a plane, is zero. If all the n points lie in a straight line, no triangles are possible and so no obtuse triangles are able to be drawn; thus for any number n, there is a possibility that no obtuse triangles can be drawn, so the least possible number of obtuse triangles drawn is zero.
