The Triangle Inequality Theorem states that the sum of two sides of a triangle must be greater than the remaining side.
If that is true for all three combinations, then your triangle is a triangle.

A. 3+4 is bigger than 5
    3+5 is bigger than 4
    4+5 is bigger than 3
B. 1+7 is NOT bigger than 10. 1+7 is smaller than 10.
C. 1.5+1.5 is bigger than 2.5
    2.5+1.5 is bigger than 1.5
D. 7+7 is bigger than 7
E. 6+6 is NOT bigger than 7. 6+6 is equal to 7.
