- Simona Riva
Simple and self-intersecting polygons
Convex and Concave Polygons
Convex polygons and interior angles
What can you say about the measures of the interior angles of a convex polygon? Do they all have a common characteristic?
Concave polygons and interior angles
What can you say about the measures of the interior angles of a concave polygon? Do some of them have a common characteristic?
Convex polygons, concave polygons and their diagonals
Describe the difference between the position of the diagonals of a convex and of a concave polygon, with respect to the portion of the plane enclosed within its sides.
