The side of the rhombus is 8 cm and the acute angle is 60 degrees. Find the smaller diagonal and perimeter of the rhombus
Since the lengths of all sides of a rhombus are equal, then Ravsd = 4 * AB = 4 * 8 = 32 cm.
In triangle ABD, AB = AD = 8 cm, angle BAD = 60, then triangle ABD is equilateral, BD = AB = AD = 8 cm.
Answer: The length of the smaller diagonal is 8 cm, the perimeter is 32 cm.
