How many triangles can you make from straws with the lengths 2,1,2 inches?

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
