Most areas on the west side (West Hollywood, Culver City, Beverly Hills) and to the north (Silver Lake, Los Feliz) have very walkable areas are all relatively safe. Downtown LA still has a sketchy history but in reality is very safe these days. It's one of the places in the city where there are legitimate lofts.
A concave polygon is defined as a polygon with one or more interior angles greater than 180Â°. It looks sort of like a vertex has been 'pushed in' towards the inside of the polygon. Note that a triangle (3-gon) can never be concave. A concave polygon is the opposite of a convex polygon. See Convex Polygon. In the figure above, drag any of the vertices around with the mouse. Take note of what it takes to make the polygon either convex or concave. Also change the number of sides.
In elementary geometry, a polygon /ËpÉlÉªÉ¡Én/ is a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit. These segments are called its edges or sides, and the points where two edges meet are the polygon's vertices (singular: vertex) or corners.The interior of the polygon is sometimes called its body. An n-gon is a polygon with n sides.A polygon is a 2-dimensional example of the more general polytope in any number of dimensions. The basic geometrical notion of a polygon has been adapted in various ways to suit particular purposes.n n-gon is a polygon with n sides.
