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.

A concave line is a line that caves in.
A geometric star shape is concave. A star that is in the sky is convex.
pole is the geometric center of the reflecting surface.

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.
Concave, because you can connect the corners from the outside.
Concave is a property of [irregular] polygons. A parallelogram cannot be concave.
no concave mirror is in shape of concave mirror
plano concave
A star shape can be classified as convex or concave depending on its specific design. A convex star, like a typical five-pointed star, has all its interior angles less than 180 degrees, meaning that any line segment drawn between two points inside the star will lie entirely within it. In contrast, a concave star has at least one interior angle greater than 180 degrees, resulting in indentations that create "inward" points. Thus, whether a star is convex or concave depends on its geometric properties.
