➤
➜ let the ABCD be the rhombus
➜ AC and BD bisect at point O
___________________________
➤
➜ AC = 16 cm , BD = 12 cm
➜ diagonals of the rhombus bisect at right angles.
___________________________
➤
➜ AO = = 8 cm
➜ BO =
➜ In right angled ∆AOB ,
➜ by using Pythagorean theorem,
➜ AB ^ 2 = AO ^2 + BO ^2
➜ AB ^ 2 = 8^2 + 6^2
➜ AB ^2 = 64 + 36
➜ AB ^2 = 100
➜ AB = √100
➜ AB = 10 CM
