A. Determine whether each given figure is a polygon or not. For those that are polygons classify them as convex or nonconvex. B. Classify the given polygons according to the number of sides.
Answer (1)
Step-by-step explanation:To determine whether a polygon is a concave or convex polygon. You must need a ruler. One of the ways to determine them is to use a ruler and measure the diagonals of the polygon (invisible line from Vertex to Vertex). If the diagonal stays in the polygon, it's called a convex polygon, but if atleast one diagonal is out of the polygon it will be a concave polygon. Another way, is to measure all the interior angles of the polygon, if all angles are less than 180 degrees it's convex, but if atleast one angle is above 180 degrees it's a concave polygon.
