if O is a point within a quadrilateral ABCD , show that OA+OB+OC+OD>AC+BD
Asked by gspublicschool | 8th Sep, 2018, 06:04: AM
If point O is in the quadrilateral, then join O to A, B , C and D
Now in triangle OAB
OA+OB>AB ... since sum of two sides is always greater than third
now if we add any term on left hand side the term will be even more greater
Similarly look in the triangle OBC,
now add OA and OD on left hand side
