Answer:

  • Option A
  • Option C
  • Option D

Explanation:

Let's verify all the options.

Option A:

  • 12 + 15 > 25
  • ⇒ 27 > 25 (True)
  • ⇒ 12 + 25 > 15
  • ⇒ 37 > 15 (True)
  • ⇒ 15 + 25 > 12
  • ⇒ 40 > 12 (True)

Option B:

  • 3 + 3 > 6
  • ⇒ 6 > 6 (False)

Option C:

  • 2 + 3 > 4
  • ⇒ 5 > 4 (True)
  • ⇒ 2 + 4 > 3
  • ⇒ 6 > 3 (True)
  • ⇒ 3 + 4 > 2
  • ⇒ 7 > 2 (True)

Option D:

This has to be true because this triangle is classified as an equilateral triangle, which is a triangle.

Hence, Option A, C, and D are correct.
