There are two versions of the triangle inequality. One requires ...

a + b > c

for any triple of side measures a, b, c.

The other allows ...

a + b ≥ c

which admits "triangles" that have zero height and look like line segments.


34+27=61>58

It satisfies the inequality , Thus form the triangle.


29+9=38\ge38

It satisfies the inequality , Thus form the triangle.
