Khouyang:

What is the greatest number of obtuse angles a triangle can contain

Mercury:

@Khouyang some reminders: an obtuse angle is an angle over 90 degrees all angles in a triangle must sum to 180 degrees so let's start with a triangle having 1 obtuse angle ---> after considering 1 obtuse angle, how many degrees are left? how many more, if any, obtuse angles can you add, while staying within the 180-degree constraint?
