A polygon is convex if you can take any two points inside the polygon and connect them with a line segment that is completely contained by the polygon. A non-convex polygon is one which contains at least two points such that the line joining them does not lie entirely inside the polygon.
No. In a convex polygon, all the internal angles are smaller than 180 degrees.
A convex polygon
A regular polygon.
A convex polygon.
No
A convex polygon.I suspect that what you mean is a convex polygon.
A circle, semicircle, segments or sectors of circle, ellipse, segments or sectors of ellipses, cardiods, closed convex wriggly shapes.
is this a polygon? is it concaver or convex
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
a polygon is convex
A convex polygon is one with no angle greater than 180 degrees. A non-convex polygon is one that is not without such an angle.
Yes, the angle sums will be the same regardless of whether or not it is a convex polygon.
Is a concave polygon.

A polygon is convex if you can take any two points inside the polygon and connect them with a line segment that is completely contained by the polygon. A non-convex polygon is one which contains at least two points such that the line joining them does not lie entirely inside the polygon.
No. In a convex polygon the sum of the interior angles is (n-2)*180 deg where n is the number of interior angles. In a non-convex polygon this is not necessarily true.
