No, Polygon B is regular because all the sides of the polygon measure the same.
		No, Polygon B is convex because all the interior angles measure less than 180 degrees.
		Yes, both have all sides that do not measure the same and one angle each that measures greater than 180 degrees.
		Yes, all the sides and interior angles of Polygon A do not measure the same, and only one angle in Polygon B measures greater than 180 degrees.
