Convex polygons Convex polygons are shapes that are shapes that curve out of a curve out of a usual shapeusual shape

Concave polygons Concave polygons are shapes that are shapes that curve inward (if you curve inward (if you can draw a straight can draw a straight line from inside one line from inside one part of the shape part of the shape going out of the going out of the shape then inside shape then inside again to the other again to the other side, it is concave) side, it is concave)
