(1)[(PA)^2+(PB)^2+(PC)^2+(PD)^2]/[(QA)^2+(QB)^2+(QC)^2+(QD)^2] =

(2)let Line L joining any two adjacent points of square (may be vertex points ,this is the wording used in book) then locus of center of circle C is -----

(3)Line L passes through A and C and a line parallel to AC passes through B. if locus of S cuts this line at two points T1 and T2 and diagonal BD at T3.Find area formed by TRIANGLE T1T2T3.
