[" 8.If "o." is a point within a quadriliteral "ABCD" ,shan "],[qquad OA+OB+OC+OD>AC+BD" ."]

If O is a point within a quadrilateral ABCD, show that OA+OB+OC+OD gt AC+BD.

In the quad. ABCD is a point inside it. Find that OA+OB+OC+OD>AC+BD.

O is any point inside a rectangle ABCD. Prove that OB^2+OD^2=OA^2+OC^2 .

If 'O' is any point in the interior of rectangle ABCD, then prove that : OB^(2) + OD^(2) = OA^(2) + OC^(2)

O is any point inside a rectangle ABCD, Prove that OA^(2) + OC^(2)= OB^(2) + OD^(2)

If 'O' is any point in the interior of rectangle ABCD,then prove that: OB^2+OD^2=OA^2+OC^2 .

O' is any point inside a rectangle ABCD. Prove that OB^2+OD^2=OA^2+OC^2

In fig., O is a point in the interior of a triangle ABC, OD bot BC, OE bot AC and OF bot AB. Show that:- OA^2+OB^2+OC^2-OD^2-OE^2-OF^2=AF^2+BD^2+CE^2 .

O is any point inside a rectangle ABCD. Prove that OB^(2)+OD^(2)=OA^(2)+OC^(2) . DEDUCTION In the given figure, O is a point inside a rectangle ABCD such that OB=6cm, OD=8 cm and OA=5 cm, find the length of OC.
