In the figure ABCD is a parallelogram `bar(DE) _|_ bar(AB),bar(BG) _|_ bar(CD)` and EBGD is a square. If BG=12cm and BC=13cm. Then the value of AB is

In the figure above, ABCD is a parallelogram, bar(BE)bot bar(AB), bar(BG)bot bar(CD) , and EBGD is a square. If BG=12 cm and BC=13 cm , then find AB.

OACB is a parallelogram with bar(OC)=bar(a), bar(AB)=bar(b)" then "bar(OA)=

If ABCD is a parallelogram such that bar(AB)=bar(a), bar(BC)=bar(b)" then "bar(AC), bar(BD) are

If ABCDE is a pentagon, then bar(AB) + bar(AE) + bar(BC) + bar(DC) + bar(ED) =

In the parallelogram if bar(AB)=bar(a) and bar(AD)=bar(d) then find bar(BD) .

If ABCD is a square, then bar(AB) + 2 bar(BC) + 3 bar(CD) + 4 bar(DA) =

ABCD is a parallelogram.bar(AP) bisects /_A and bar(CQ) bisects /_C.P lies on bar(CD) and Q lies on bar(AB0) .Show that

In the figure 11.34, ABCD is a quadrilateral in which bar(AB) = bar(AD) and bar(BC) =bar(DC). Diagonals bar(AC) and BD intersect each other at O.Show that-
