No it's impossible. an obtuse angle=greater than 90 degrees a triangle has three angles, of which all add up to 180 lets say one angle is 91, obtuse right? now multiply it by three and you get 273, which is greater than 180-not a triangle

No because an equilateral triangle has 3 equal acute angles of 60 degrees
Nope, that is not possible. Equilateral triangles always have three 60 degree angles, which are all acute.
You can draw a triangle with two obtuse angles in a sphere
An equilateral triangle means a triangle with all three sides with equal dimensions. For drawing an equilateral triangle first you will have to choose a measurement to draw the sides of the triangle. For example, lets take the side to be 4cm. When you draw the base of 4cm you will have to draw the other two sides of 4cm as well. Thus an equilateral triangle is constructed..
Yes providing its other two acute angles are of different sizes
