Can segments with lengths of 15, 20, and 36 form a triangle? If so, would the triangle be acute, right, or obtuse?

The correct answer for this question is: "Cannot form a triangle. (15+20) is not greater than 36."

In order to form a triangle, the sum of the two sides must be greater than that of the third side. From the given lengths of the triangle, 15, 20, 36

15 + 20 < 36
15 + 36 > 20
20 + 36 > 15

But the first one is "less than"

I believe that the most fitting answer for this question would be that sides of this length cannot form a triangle. The two shorter sides, 15 and 20, would have to be greater than 36 when added together, and they only equal 35. So, since they cannot form a triangle, you would not need to worry about what kind of triangle they would form. Hope this helps.
