In Fig , if `LM||CB and LN || CD` , prove that `(AM)/(AB) =(AN)/(AD)`

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

In the figure DE"||"AC and DF"||"AE . Prove that (BF)/(FE)=(BE)/(EC) . OR In fig LM"||"CB and LM"||"CD , Prove that (AM)/(AB)=(AN)/(AD)

In Delta ABC , DE || BC and CD || EF . Prove that AD^(2) = AF xx AB

In the adjacent figure, AB = BC and AC = CD . Prove that : /_ BAD : /_ ADB = 3 : 1.

In Fig .D is a point on side BC of DeltaABC such that (BD)/(CD) =(AB)/(AC) prove that AD is the bisector of angleBAC.

In the figure, If AC=BD then prove that AB=CD.

If AD and PM are median of triangles ABC and PQR respectively where Delta ABC - Delta PQR , prove that (AB)/(PQ) = (AD)/(PM) .

In Delta ABC , AD bot BC and AD^(2)= BD xx CD . Prove that AB^(2) + AC^(2) = (BD + CD)^(2)

In Delta ABC , BD : CD = 3 : 1 and AD _|_ BC . Prove that 2(AB^(2) - AC^(2)) = BC^(2) .
