Practice Problems to Determine if Three Side Lengths Are a Triangle


To determine if the three side lengths can form a triangle, follow these steps:


* Sort the three side lengths in order from least to greatest.
* Check if the sum of the two smallest sides is greater than the length of the largest side. If this is true, then the three side lengths can form a triangle. If not, then they cannot form a triangle.
