Solve the cryptarithm : `overline(AB)+overline(BA)=overline(DAD)`

Solve the cryptarithm :AB+BA=DAD

If ABCDEF is a regular hexagon inscribed in a circle with centre O, then overline(AB)+overline(AC)+overline(AD)+overline(AE)+overline(AF)=

overline(AB)-overline(CB)+overline(DA)+2overline(CD)=

ABCDE is a pentagon. The resultant of the vectors overline(AB), overline(AE), overline(BC), overline(DC), overline(ED) and overline(AC) in terms of overline(AC) is

Measure all the line segments in the figure given below and arrange them in the ascending order of their lengths. Line segments overline(AB) , overline(AC) , overline(AD) , overline(AE) , overline(BC) , overline(BD) , overline(BE) , overline(CD) , overline(CE) , overline(DE)

If overline(a), overline(b), overline(c) be three vecotrs such that overline(a)timesoverline(b)=overline(c), overline(b)timesoverline(c)=overline(a), overline(c)timesoverline(a)=overline(b) , then

If ABCDE is a pentago, then overline(AB)+overline(BC)+overline(CD)+overline(DE)-overline(AE)=

If ABCD is a quadrilateral, then 2overline(AB)+3overline(BC)+2overline(CD)+overline(DA)+overline(CA)+overline(DB)=
