Question

what do you mean by concave and convex polygon​

Answer 1

Answer:

A polygon is said to be convex if all the interior angles of the polygon are less than 180o. On the other hand a polygon is said to be concave if one or more than one interior angles of the polygon is greater than 180o.

Answer 2

Answer:

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.
