For triangle ABC , a,b,c,r, R have their usual meanings

                                column I                                                                                  COLUMN II

1)if b cos²A/2 + acos²B/2 = 3c/2                                                         P) 1/2

where a= , b=1 then c is greater than                                                                        Q) 1

2)R=a/2 and r=c/k Then k must be greater than                                  R) 3/2

3)Circumcenter is at origin  and a sinA . P(x,y) lie inside               S)2

the circumcircle and k=1 /8|xy|  then k must be greater

4) 'G' is centriod and the angle between GB and GC is obtuse , Then a² is greater

than  (b-) , c- )
