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.
No.
Convex: any line drawn through the polygon (and not tangent to an edge or corner) meets its boundary exactly twice.Non-convex: a line may be found which meets its boundary more than twice.Simple: the boundary of the polygon does not cross itself. All convex polygons are simple.Concave: Non-convex and simple.Star-shaped: the whole interior is visible from a single point, without crossing any edge. The polygon must be simple, and may be convex or concave.hope it can help you :)
