The flag of Qatar consists of a serrated line with nine points, so technically there are no triangles. If one considers each point to be a triangle extension of the solid color, then there are 19 triangles (9 white, 10 red).
10 triangles make a decagon
10 triangles
10-2 = 8 triangles
Yup, it follows the 3, 4, 5 rule (or in this case 6, 8, 10). Triangles with those ratios in the lengths of its sides are always right triangles

A decagon has ten sides and a triangle has three, so 5 decagons and 4 triangles have (5*10)+(4*3) = 62 sides altogether.

10 triangles....
There are 3 to 10 triangles in a star.
10 triangles
10-2 = 8 triangles
Triangles are needed to form polygons of 3 sides or more as for instance a 6 sided hexagon needs 4 triangles and a 10 sided decagon needs 8 triangles.

There cannot be parallel lines in any [plane] triangles.
No. For example the triangles with sides {3, 4, 5} and {6, 8, 10} are similar but not congruent.
Only 3 if the sticks can only be used once in each triangle.
