A geometric star shape is concave. A star that is in the sky is convex.
No, a concave equilateral pentagon is not possible. In a concave polygon, at least one interior angle must be greater than 180 degrees, which would make it impossible for all sides to be of equal length while maintaining the necessary geometric properties of a pentagon. Thus, an equilateral pentagon must be convex.
Concave, because you can connect the corners from the outside.

Thus, an equilateral pentagon must be convex.
The opposite of convex is concave. Concave shapes have an inward curve, while convex shapes have an outward curve.
