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.
The easiest method is to split the octagon up into triangles and sum the areas of the triangles.
There are 6 triangles in an octagon
Eight triangles of equal size form a regular octagon.

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.
