Convex Polygon
From Latin: convexus "vaulted, arched"
Definition: A polygon that has all interior angles less than 180°
(Result: All the vertices point 'outwards', away from the center.)
Try this Adjust the polygon below by dragging any orange dot. If any vertex points 'inward' to towards the center of the polygon, it ceases to be a convex polygon.

A convex polygon is defined as a polygon with all its interior angles less than 180°. This means that all the vertices of the polygon will point outwards, away from the interior of the shape. Think of it as a 'bulging' polygon. Note that a triangle (3-gon) is always convex.

A convex polygon is the opposite of a concave polygon
