Question

Henry draws an obtuse triangle how many obtuse angles does Henry's triangle have? Please eye help

Answer 1

The sum of all three angles in any triangle is always 180 degrees. So in obtuse triangle there is only one obtuse angle (more than 90 degrees). If we have for example an obtuse angle of 91 degrees, then two other angles have to fit in 89 degrees which makes it impossible for any of them to be obtuse.
