A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
An obtuse triangle has 1 obtuse angle and 2 acute angles
No. An obtuse angle is only one of several types of angles.
An obtuse angle
Sometimes it has an obtuse angle. If it is just a parallelogram or a rhombus, then it has two obtuse angles.\. If it is also a rectangle or a square, then it has four right angles.
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.

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.
They will be acute angles.
No. An obtuse angle is only one of several types of angles.
Yes. It must have an obtuse angle.
An obtuse angle
Sometimes it has an obtuse angle. If it is just a parallelogram or a rhombus, then it has two obtuse angles.\. If it is also a rectangle or a square, then it has four right angles.
It is an obtuse triangle having 1 obtuse angle and 2 different acute angles Or it is an isosceles triangle having 1 obtuse angle and 2 equal acute angles
A traditional kite shape (a point at the top, then widest about 1/3 of the way down, then tapering to another point at the bottom) has one, two or three obtuse (>90 degree) angles. The two angles at the widest point, about 1/3 of the way from the top, are generally obtuse, but don't have to be. The bottom angle is almost never obtuse. The top angle is sometimes obtuse. So if the top angle is obtuse but the side angles are not, a kite shape has one obtuse angle. If the top angle is not, but the side angles are, it has two obtuse angles. If the top and side angles are obtuse it has three.
If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.
