Question

Q2.1) Let ABCD be a quadrilateral in N.G. with right angles at B
&C. Let AB=a, CD=b and m... (<DAB)=p, m(<ADC)=a.
Show that i) a=b if and only if a =p li) if a > then a>b.
II) Let L1,L2 be two coplanar lines in the H.G..Let P,A,B be three
points on L, and; Q,C,D be three points on Lį such that A is
between P and B, while C is between Q and D. Assuming the
angles at P,Q,C,D are right angles. Prove that
PQ <AC < DB.​
