a polygon in which any line segment connecting two points of the polygon has no part outside the polygon.
A convex polygon.I suspect that what you mean is a convex polygon.
Yes, the angle sums will be the same regardless of whether or not it is a convex polygon.
Is a concave polygon.
No, a scalene triangle, for example, is a convex poygon but it is not regular.
Not
A simple polygon that is not convex is called concave, non-convex or reentrant. A concave polygon will always have an interior angle with a measure that is greater than 180 degrees.
A convex polygon.I suspect that what you mean is a convex polygon.
In a non-convex (or concave) polygon, at least one interior angle is a reflex angle. An alternative definition is that if you take any two points inside a conves polygon, the line joining them is wholly inside the polygon.
A convex hexagon is a six-sided polygon in which all interior angles are less than 180 degrees.
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.
is this a polygon? is it concaver or convex
a polygon with 6 sides * * * * * The fact that is has six sides makes it a hexagon but that does not explain ""convex". A convex polygon is one in which none of the angles is a reflex angle. An alternative definition of convex is that a line joining any two points inside the hexagon is wholly inside the shape.
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.
It is convex if you look at it from the inside but it is not any kind of polygon.
Is a concave polygon.
