Answer:
I'll list them below
Explanation:
1. Yes. The shorter sides equal the largest side
2. No. The shorter sides are greater than the largest side
3. No. The shorter sides are greater than the largest side
4. No. The shorter sides are greater than the largest side
In order to figure these out, you have to add the 2 shorter sides. If the sum is equal to the largest side, it is a right triangle. If they are less or greater, it isn't.
