The hands on a clock!
In normal geometry, it's not possible to make a triangle with two obtuse angles. It is possible to make a triangle with two obtuse angles in spherical geometry -- it's a kind of "spherical triangle". It is possible to make a triangle with two obtuse angles in some kinds of non-Euclidean geometry -- it's a kind of "non-Euclidean triangle".
An obtuse angle is an angle between (but not including) 90 and 180 degrees, so some obtuse angles would be 91 degrees, 179 degrees, and 142 degrees.
Yes, a Triangle can have 3 obtuse EXTERIOR angles of measure 120° ONLY in the case of an equilateral Triangle. OTHERWISE, a Triangle always has 2 obtuse Exterior angles and 1 acute Exterior angle.
Some have one obtuse interior angle, others have none. A triangle can have no more than one obtuse angle.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. In addition there are concave octahedra. Some of these will have no obtuse angles, others will have several.

some triangles and rhombuses. trapoziods do not have acute angles it has obtuse angles. :)

No because any triangle must have a total of 180 degrees when the angles are added together and with 2 obtuse angles the sum would be greater than 180. A triangle can only ever have one obtuse angle.
Some trapezoids have 2 acute angles, 2 obtuse angles, 1 pair of parallel lines, 1 short side, and 1 long side.
