8 triangles will fit inside a 10 sided decagon
By tridecagon, I suppose you are referring to a 13 sided shape. In any shape, you could draw however many triangles you wanted to. If you are after triangles formed by a line from the corners of the shape to the centre, a tridecagon (after the first few shapes, mathematicians usually just use the term n-gon so your 13 sided shape would be called a 13-gon), would contain 13 triangles formed in this way.
A tridecagon has 13 angles
6 Triangles!!
In geometry, a triskaidecagon has 13 sides and 13 angles. A triskaidecagon is also called a tridecagon. A tridecagram is a 13-sided star polygon.
