Which of the following measures could form the sides of a triangle?
I) 3, 3, 5
II) 6, 6, 12
III) 1, 2, 3
- I only
- II only
- III only
- I and II only
- II and III only
Answer(s): A
Explanation:
The sum of the measures of the two shorter sides of a triangle must be greater than the longest side. Since 3 + 3 > 5, statement I works. Since 6 + 6 = 12 and 1 + 2 = 3, they do not form the sides of the triangle. The answer is statement I only.
