8-2 = 6 triangles
In a convex octagon, you can form triangles by selecting any three vertices. Since an octagon has 8 vertices, the number of ways to choose 3 vertices from these 8 is calculated using the combination formula ( \binom{n}{r} ), where ( n ) is the total number of vertices and ( r ) is the number of vertices to choose. Thus, the number of triangles formed is ( \binom{8}{3} = \frac{8!}{3!(8-3)!} = 56 ). Therefore, 56 triangles can be formed in an octagon.

get a cut out shape of octagon, then get cut out triangles and try to fit in the triangles covering all the octagon but here is the solution... j
Yes, an octagon could be considered to be made out of 8 triangles.
An octagon is made up from six triangles each containing 180 degrees.
There are 6 triangles in an octagon
Eight triangles of equal size form a regular octagon.
There are 6
There are six triangles in an octagon. In any convex polygon, there are two less triangles than the number of sides. So a octagon which has 8 sides, contains 6 triangles.

None.
In an octagon, there are 20 equilateral triangles. Each side of the octagon can form two equilateral triangles with the adjacent sides, resulting in 8 equilateral triangles. Additionally, the diagonals of the octagon can form 12 more equilateral triangles. Therefore, the total number of equilateral triangles in an octagon is 8 + 12 = 20.
