It is concave because it is going in so it is going in the cave
concave, equilateral
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.

If it's a regular hexagon, it can't be concave. If it's an irregular hexagon,then it can be concave if it wants to, but it doesn't have to be.

A concave hexagon is a hexagon that has one or two reflex angles. With one reflex angle, it will resemble a chevron - like a stripe on a police or army uniform, or the letter V which has thickness. With two reflex angles, it will resemble an hourglass with straight sides.
A concave irregular hexagon can have up to 6 right angles. A convex irregular hexagon can have up to 3 right angles.
