Want this question answered?
An infinite number are possible.
It is possible to divide a hexagon into 4 or more - up to infinitely many - triangles.
A polyhedron with two congruent triangles. There are very many possible configurations.
You have to specifically give the problem with the dots, but it can form all equilateral triangles.. .. . .. . . .
A triangle has 6 parts ... 3 sides and 3 angles. It's possible for two triangles to have as many as 3 of their parts congruent, and the triangles still not be congruent.
33 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.
i dont know because its to give you that answer
a pyramid can use any triangles possible.
there are 27 triangles in a triangle
Yes and they would be called similar triangles
There are 15 triangles in a 17-agon
In general? Infinite. In the picture you were looking at when you asked this question? I don't know.
15 triangles
15 triangles!!!!!!!!!!
4 are formed
There are infinitely many possible answers. One of these is a icosahedron.
