It is a convex polygon.
A concave polygon.
A convex polygon
It should be convex
Not too sure of the question but the only polygon that has no diagonals is a triangle.
A diagonal is a straight line connecting two non-consecutive points in a four or more sided polygon without overlapping any of the sides.
A diagonal from a polygon is a line segment that joins two nonconsecutive points.
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.
Yes, but not a polygon (or polyhedron).Consider a quadrilateral with one diagonal. The end points of the diagonal are at odd vertices while the other two are even.
If one of its exterior angles is 30 degrees, then it is a star with 6 points and 12 sides. 360 degrees / 30 degrees = 12 angles It is a regular dodecahedron.
it becomes a Star polygon
The vertices are the "points" of a polygon.
no because a polygon can not have curved edges,points,sides,ect.
