There are 3 side lengths:

4 cm, 1 cm, and 6 cm. How many triangles can be formed?

One Triangle

Many Triangles

Zero Triangles

one triangle

Step-by-step explanation:

Determining if three side lengths can make a triangle is easier than it looks. All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.[1]
