True or false. the segments below could form a triangle, 9, 4, 11

natita [175]

True. There are two ways to solve this; one, a shortcut , which is when you add each of them up and they are greater than each other (9+4= 13, which is greater than 11), or you could also use the Pythagorean theorem to solve the problem; the formula is
