Consider a triangle AOB, whose side OA = OB, as half of the diagonals, which are halved at the intersection, angle O = 60, side AB = 4 cm.
If in an isosceles triangle at least one angle is equal to 600, then this triangle is equilateral.
Then AB = AO = BO = 4 cm.
Diagonals AB = BC = 2 * AO = 2 * 4 = 8 cm.
Answer: The length of the diagonals of the rectangle is 8 cm.
