Place GHI so that G is at B and H is at A. You now have quadrilateral AIDC (IBD is a straight line).
Place JKL so that L is at D and J is at B. Now AIBKDC is the concave hexagon.
To form a concave hexagon from four triangles, you can arrange the triangles such that two of them share a common side, while the other two are positioned to create indentations. For example, place two triangles adjacent to each other to form a larger triangle, then attach the third triangle to one side, and the fourth triangle in a way that creates an inward point, forming a concave shape. Make sure that the angles of the triangles allow for the necessary concave indentations, resulting in a six-sided figure with at least one inward angle.
You need at least four triangles, or at least three trapeziums. Or two triangles and one trapezium.
First make a regular hexagon. Then take any one triangle and slide it through two heights so that it's base is on what was the opposite side. You will have an irregular, concave hexagon, shaped somewhat like an arrowhead.
6 polygon triangles make a hexagon
No?
You start creating a concave hexagon from four triangles by placing the smallest triangle in the middle to serve as a base for the other three. Line up the bases on each triangle with the sides of the smallest one to end up with six sides forming a concave hexagon.
Put four equilateral triangles so that each one of them has a vertex at a single point and the triangles abut one another. The shape will be 4/6 (= 2/3) of a regular hexagon.

3 triangles make up a hexagon.
First make a regular hexagon. Then take any one triangle and slide it through two heights so that it's base is on what was the opposite side. You will have an irregular, concave hexagon, shaped somewhat like an arrowhead.

pentagon i think?
How can a you make a hexagon using a trapozid and 2 triangles
