The quadrilateral formed by joining the midpoints of the quadrilateral $PQRS$ taken in order, is a rectangle, if

If the angles $A,B,C,D$ of the quadrilateral $ABCD$ taken in order are in the ratio $3:7:6:4, ABCD$ is 

The figure obtained by joining midpoints of sides of rhombus, taken in order is

If $APB,CQD$ are two parallel lines, then the bisectors of angles $APQ,BPQ,CQP,PQD$ form

If bisectors of $\angle A \& \angle B$ of quadrilateral $ABCD$ intersect each other at $P$ and the bisectors of $\angle B \& \angle C$ at $Q$, bisectors of $\angle C \& \angle D$ at $R$ and that of $\angle D \& \angle A$ at $S$, then $PQRS$ is a
