Which side lengths allow you to construct a triangle?

Answer 1

Suppose a is one side, b is the other side, and c is the last side.

If a+b > c,

b+c > a,

c+a > b,

you can construct this traingle.

Or in simpler terms, any two side lengths'sum has to be bigger than the third.

E.G. If one side was 2, one side was 5, and the other side was 2, than

you aren't able to construct the traingle because

2+2 isn't bigger than 5.

BUT If one side was 2, the other side was 2, and the last was 3, than you could because

2+2>3, 3+2 > 2, and 2+3 > 2.
