+23254 If the three numbers represent the sides of a triangle, then call 'c' the length of the largest side, and 'a' and 'b' the lengths of the other two sides.
∠C is the angle opposite side 'c' and since side c is the largest side of the triangle, ∠C will be the largest angle of the triangle.
If c² = a² + b², then the triangle is a right triangle because ∠C is a right angle.
If c² > a² + b², then the triangle has an obtuse angle at ∠C.
If c² < a² + b², then the triangle has an acute angle at ∠C, making all the angles acute.
Acute angle - all angles are less than 90 degrees
Obtuse angle - all the angles are more than 90 degrees
