How many acute angles does a scalene triangle have? - Answers

The only rule for a scalene triangle is that it must have no equal angles (as a consequence, it has no equal sides as well). Outside of that, it can have any angles possible for a triangle.The sum of the angles in every triangle must be 180º. Reminding that an acute angle has less than 90º, an scalene triangle may have 3 acute angles (for example, 61º, 60º and 59º) or 2 acute angles (for example, 120º, 40º and 20º).It is impossible to have a triangle with 1 or less acute angles, since for 1 acute angle we would need the other 2 to be greater or equal than 90º, which is impossible - we cannot have a 0º or negative angle in a triangle.
