Answer:
None
Explanation:
A three-sided polygon is a triangle.
In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
2 cm + 3 cm = 5 cm
5 cm = 5 cm
Since the sum of the lengths 2 cm and 3 cm is not greater than 5 cm, these three segment lengths cannot form a triangle.
