Answer:
You can make one triangle with these lengths
Step-by-step explanation:
we know that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Verify if the lengths satisfy the triangle inequality theorem
1) 2+1 > 2
3 > 2 ------> is true
2)2+2 > 1
4 > 1 -----> is true
so
The lengths satisfy the triangle inequality theorem
therefore
You can make one triangle with these lengths
