ABCD is a square if a diagonal AC equal to 10 cm then the side of the square is
ayeeclique:
In square we know that the diagonals bisect ech other at right angles. Therefore, if we consider ∆AOD (naming point of intersection to be O) then angle AOD =90 degrees . Therefore by using 45-45-90 theorem , which states thta the side opposite to 45 degrees is 1/√2 times hypotenuse. We get , 5=1/√2 (AO). Therefore, AO= 5√2cm.

AC^2 = 2AB^2
100 = 2AB^2
AB^2 = 50
AB = √50
AB= 5√2
