The answer varies depending on the exact type of geodesic dome you are using. A 2 frequency and 4 frequency geodesic domes use 20 equilateral triangles despite the two-frequency having many more faces than the 2 frequency where the 3 frequency geodesic dome (150 sided) uses none at all. The above calculations, however, are only common to a certain architectural model. Assuming the domes are built mathematically instead of according to architectural integrity, the number of equilateral triangles in a "pure" dome, a geodesic sphere, is exactly equal to the number of faces, by definition.
5 equilateral triangles.
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.
6There are six.

The minimum numbers of congruent faces are as follows: On an equilateral triangular prism: one pair of triangles On a right equilateral triangular prism: one pair of triangles and one triplet of rectangles.
A geodesic dome is made up of many triangles and very strong.
Six equilateral triangles are found in a regular 6 sided hexagon
3 because equilateral triangles are triangles that have 3 congruent sides.
5 equilateral triangles.
Equilateral triangles have three congruent sides and three congruent angles

All triangles - equilateral or not - have three straight sides.
Equilateral triangles have 3 perpendicular bisectors
