An equilateral triangle is NOT concave. The sides only push out, and they never cave in. An equilateral triangle is convex. I hope that helped all who needed.

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.

It depends entirely on their relative shapes and sizes. They could make a triangle, a parallelogram, a square, or a pentagon or even a concave heptagon.
If they share a part or whole of a side and provided they do not overlap, then depending on the shape of the triangles, the result can be a triangle, quadrilateral or a concave pentagon. Otherwise you can get other shapes such as a 6-pointed star.
