` Delta ABC ~ Delta DEF `, Prove that ` (AB)/(DE) = (AB + BC + AC) / ( DE + EF +DF ) `

In Delta ABC and Delta DEF , we have (AB)/(DE)=(BC)/(EF)=(AC)/(DF)=5/7 , then ar (Delta ABC) : ar (Delta DFR) =?

In Delta ABC and Delta DEF , it is given that (AB)/(DE)=(BC)/(FD) then they will be similar when

If Delta ABC~Delta DEF such that 2AB=DE and BC=6 cm find EF.

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

In Delta ABC and Delta DEF is (AB)/(DE) = (BC)/(DF) then they will be similar if:

In Delta ABC and Delta DEF , if AB = EF, BC= DE and CA = FD, then

In Delta ABC and Delta DEF , AB = DE, AB|| DE , BC = EF and BC|| EF . Vertices A, B and C are joined to vertices D, E and F respectively (See fig.) Show that AC=DF.

In Delta ABC and Delta DEF , AB = DE, AB|| DE , BC = EF and BC|| EF . Vertices A, B and C are joined to vertices D, E and F respectively (See fig.) Show that AC=DF.

In Delta ABC and Delta DEF , AB = DE, AB|| DE , BC = EF and BC|| EF . Vertices A, B and C are joined to vertices D, E and F respectively (See fig.) Show that quadrilateral ABED is a parallelogram.

In Delta ABC and Delta DEF , AB = DE, AB|| DE , BC = EF and BC|| EF . Vertices A, B and C are joined to vertices D, E and F respectively (See fig.) Show that quadrilateral ABED is a parallelogram.
