1) The answer is B, 2) the answer is D, method just put all points and get know the graph of each quadrilateral
3) the measure of one angle in a regular n-gon is given by the following main formula measure of interior angle= (n-2)*180°/n,
so for n=16, we have 14*180°/16=157.5°
4) the answer is A, because 360/5=72 > 40=360/9
