In Fig.
if AC = BD, then prove that AB = CD.

In the Fig. If AB = AD . Prove that AB > CD .

In Fig if AD bot BC , prove that AB^2 + CD^2 = BD^2 + AC^2 .

In Fig. , AB > AC , show that AB > AD .

In Fig. , AB > AC , show that AB > AD .

In the fig. prove that: AD+AB+BC+CD>2AC.

In given figure AB = AC and BD = DC. Prove that DeltaABD~=DeltaACD

In fig., LM || CB , and LN||CD.Prove that (AM)/(AB)=(AN)/(AD) . .

Diagonals AC and BD of quadrilateral ABCD interset at O such that OB = OD , If AB = Cd, then show that : ar(DCB) = ar(ACB)

In ABD is a triangle right angled at A and AC bot BD. Show right angled at A and AC bot BD. Show that AB^(2) = BC. BD

IN the fig. AD=BC and BD=CA. prove that angleADB=angleBCA and angleDAB=angleCBA
