How do you know if a triangle is obtuse

WebSep 17, 2024 · How do you find the third side of an obtuse triangle? Square the length of the side opposite the obtuse angle. For the example, if the length is 4, then squaring it results in 16. Subtract the combined squares of the adjacent sides by the square of the side opposite the obtuse angle. For the example, 16 subtracted from 13 equals -3.
