In a rhombus ABCD, prove that `AC^(2) + BD^(2) = 4AB^(2)`

ABCD is a rhombus. Prove that AC^(2) + BD^(2) = 4 AB^(2)

For a rhambus ABCD , prove that 4 AB ^(2) = AC^(2) + BD^(2)

In a rhombus prove that sum of squares of sides is equal to sum of square of diagonals or, In a rhombus ABCD prove that AB^(2)+BC^(2)+CD^(2)+DA^(2)=AC^(2)+BD^(2)

In rhombus ABCD,show that 4AB^(2)=AC^(2)+BD^(2)

In a rectangle ABCD, prove that : AC^(2)+BD^(2)=AB^(2)+BC^(2)+CD^(2)+DA^(2) .

ABCD is a rhombus.Prove that AB^(2) + BC^(2) +CD^(2) + DA^(2) = AC^(2) + BD^(2)

In Delta ABC, AD_|_ BC . Prove that AB^(2) - BD^(2) =AC^(2) -CD^(2)

ABCD is a rhombus. Prove that AB^(2)+BC^(2)+CD^(2)+DA^(2)= AC^(2)+BD^(2) .

In the given figure if AD bot BC prove that AB^(2)+CD^(2)= BD^(2) +AC^(2)

ABCD is a rhombus.Prove that AB^(2)+BC^(2)+CD^(2)+DA^(2)=AC^(2)+BD^(2)
