no
Step-by-step explanation:
The two short sides, 1 and 2, do not have a sum greater than the long side, 5, so these lengths do not form any sort of triangle.

Lengths 1, 2, √5 satisfy the Pythagorean theorem, so will form a right triangle.
1² +2² = (√5)²
1 + 4 = 5 . . . . . . Pythagorean theorem is satisfied
