A geometric star shape is concave. A star that is in the sky is convex.
Yes it is.
A regular six pointed star.
because the point of origin would be on an outer point and around it the walls seem to cave in making it seem concave, in comparison to a regular polygon. When checking for concave polygons always compare what you are looking at to a regular polygon
It is a concave octagon.
A 'concave decagon' is a ten-sided shape with every other corner pushed in towards the centre. It forms a regular five-pointed star.
Yes it is.
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.

Easy answer: a star icon or the apple logo are examples of what a concave polygon looks like.A concave polygon has 1 interior angle greater than 180 degrees.you can see an example on:http://en.wikipedia.org/wiki/Convex_and_concave_polygonshttp://www.mathopenref.com/polygonconcave.html

A 'concave decagon' is a ten-sided shape with every other corner pushed in towards the centre. It forms a regular five-pointed star.
The Star Trek logo, if made into straight lines, would be a concave quadrilateral. Simply draw a triangle. Now, at any point along the sides, make a new point and move it inward and it will be a concave quadrilateral.
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.
