There are 8 triangles.

A pentagram can be created by overlapping 3 isosceles triangles of the same size. The second triangle is rotated by 70 degrees and the 3rd by 285 degrees which result in the pentagram when overlapped, creating 5 smaller triangles to form the star.

A pentagon is a shape with five corners and five equal sides. A pentagon can be divided into five equal triangles. A pentagram is a pentagon with five triangles drawn on each side, forming a star.

Pentagrams are fractals which means they are supposed to be an endless shape. The original use was to 'seal' demons into it because the shape was infinite as you could continuosly add more pentagrams inside the one outside. Based off that picture there is ten but if you were to go extra it would be an intense amount: infinite.

Explanation:

The pentagram includes ten isosceles triangles: five acute and five obtuse isosceles triangles. In all of them, the ratio of the longer side to the shorter side is φ.

There are 5 triangles counting all of the sides and one pentagon in the middle

Five triangles and a pentagon.

There are 11 triangles in a pentagram
