Question

tell me about concave and convex polygon ​

Answer 1

Answer:

A convex polygon is a polygon where all the interior angles are less than 180º. A polygon in which at least one of the angles is greater than 180° is called a concave polygon.

A concave polygon is a polygon that is not convex. ... An example of a non-simple (self-intersecting) polygon is a star polygon. A concave polygon must have at least four sides.

Answer 2

Answer:

Convex and Concave Polygons

Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
