<h2>1, 3 and 4 are true statements.</h2>Step-by-step explanation:
Notice that the given triangle has all three side different, that means it's an scalene triangle.
Additionally, the triangular inequality states that the sum of two sides of a triangle must be greater than the third side, that is
So, the first choice is also correct.
Then, we use thes triangular inequalities to find the third true statement.
We know that and
Also,
Therefore, , which means side DF must be between 5 and 13.
The third true statement is the third option.
