Given n points in the plane you draw all possible triangles whose vertices are any three of the given points Atleast how many of them are obtuse-angled 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.


How many triangles are there in a heptagon?

seven There are five triangles in a heptagon. In ay convex polygon the triangles are two less than the sides. So a heptagon which has 7 sides, contains 5 triangles.
