Since the length of the middle line of the triangle is equal to half the length of the side to which it is parallel, the sides of the triangle will be equal: 6 * 2 = 12 cm, 9 * 2 = 18 cm, 10 * 2 = 20 cm.
Determine the perimeter of the triangle.
P = 12 + 18 + 20 = 50 cm.
Answer: The perimeter of the triangle is 50 cm.
