The height of the BK is drawn in the triangle ABC. Prove that AB = BC and find the perimeter of the triangle ABC if BC = 31 cm, AK = CK = 28 cm.
Since AK = KC, the height BK is also the median, and therefore the triangle ABC is equilateral and AB = BC.
Then the perimeter of the triangle is:
P = 31 + 31 + 2 * 28 = 118 cm.
Answer: Ravs = 118 cm.
