Question: If two triangles are similar, and the lengths of the sides of the first triangle are 3 cm, 4 cm, and 5 cm, what are the lengths of the sides of the second triangle if the shortest side is 6 cm?

Options:

  1. 6 cm, 8 cm, 10 cm
  2. 6 cm, 9 cm, 12 cm
  3. 6 cm, 7 cm, 8 cm
  4. 6 cm, 10 cm, 12 cm

Correct Answer: 6 cm, 8 cm, 10 cm

Solution:

The ratio of the sides is 6/3 = 2. Therefore, the other sides are 4*2 = 8 cm and 5*2 = 10 cm.
