Answer:
No, it doesn't.
Explanation:
In order to find what makes a triangle, lets use the Triangle Inequality Theorem!
This theorem can help us show whether the sum of two side lengths of a triangle is greater than the third side or not
Here is our formula(s):
1.) a + b > c
2.) a + c > b
3.) b + c > a.
Lets make a=12, b=7, & c=5
1.) 12 + 7 > 5
19 > 5
2.) 12 + 5 > 7
17 > 7
3.) 7 + 5 > 12
10 > 12
As you can see, both numbers 1 and 2 shows to be correct but 3 is not. Therefore it doesn't make a triangle. Remember, if all the two side lengths of a triangle is greater than the third side, then it makes a triangle.
