There are 5 triangles in an heptagon
there are 14 obtuse angled triangles. to work this out, join all the vertices together, making a 7-pointed star. then count all the obtuse-angled triangles. i got 14...you might get a different answer, if so, i apologise. lol i know where u got this question from... anyway hoped i helped :)
A heptagon has 5 triangles.
A heptagon has 5 triangles.
There are 3 obtuse angles in a heptagon.
A 7 sided heptagon contains 5 triangles.
There are 5 triangles in a heptagon
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.
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.
