A right angle triangle and the third angle measures 60 degrees

An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
The third angle must be 30 degrees so it is an obtuse triangle
The 3rd angle has to be 110 degrees therefore it is an obtuse triangle
Once again the answer from The WikiAnswers Community is wrong. The triangle is an obtuse angled isosceles triangle. And, as inanimate objects, triangles are not usually prone to become pregnant!
It is an obtuse scalene triangle
