A polygon that has a line containing a side and also passing through its interior is known as a self-intersecting polygon or a crossed polygon. An example of this is a star-shaped polygon, such as a five-pointed star. In such polygons, the sides intersect themselves, creating segments that both lie on the boundary and extend into the interior.
Convex polygon. When the sides are extended, none of them pass through the polygon's interior.

It is a concave or reentrant polygon.
A concave polygon.
An interior angle is an angle defined by two sides of a polygon and that is inside the polygon. Opposite interior angles are specific pairs of interior angles, those that are opposite each other in the polygon. Alternate or opposite interior angles are also angles that lie on opposte sides of the tranversal line that cuts through parallel lines.
