If there is a picture with 3 triangles and 1 upside down the the answer to that is OBVIOUSLY 5. Lol. The 4 triangles and the triangle going around the outside of the other little triangles inside of the picture.
A heptagon has 5 triangles.
7 triangles
There are 7 triangles in a nonegon
A heptagon has 5 triangles.
Answer is easy with a diagram. Without the picture, very difficult.
In general? Infinite. In the picture you were looking at when you asked this question? I don't know.
there are 27 triangles in a triangle
There are 15 triangles in a 17-agon
15 triangles!!!!!!!!!!
no triangles
it has 13 triangles
There are no triangles.
15 triangles
depends on what size triangles and what kind of triangles?
If you are talking about the common triangle puzzle, then there are 27 triangles. There are 16 one-cell triangles, 7 four-cell triangles, 3 nine-cell triangles, and 1 sixteen-cell triangle. There is a link to the pic for you also. _______________________________________________________________________ The answer in a two dimensional way would be 27. However, if you take into account that each triangle can be turned three ways, then you can understand that there are actually 81 triangles in all. THen you could ask the question, how many triangles can fit in this space (i.e. the picture)? The answer is the first level of infinitely many, or Aleph zero. This would be by finding the midpoint of each side of the all the 1- cell triangles and creating a new triangle.
You need 3,5,7,9... triangles. They have to be equilateral triangles. 1,3,5,7... need to be upside down while 2,4,6,8... have to be right side up. ______ /\ /\ /\ / \ / \ / \ /__\/__\/__\ I know, bad picture, hopefully you get the point though.
