An obtuse angle is only one angle, however if you meant 'how many degrees?' then an obtuse angle contains more than 90 and less than 180 degrees..
A triangle can have at most one obtuse angle, but triangles do not necessarily have any obtuse angles.
There are no obtuse angles in a square. A square is a perfect 90 degree angle.
There are 3 obtuse angles. All 3 exterior angles are obtuse. (This is, admittedly, a bit of trick question!)
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.
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.
the answer is 5 each tip of the star is a acute angle and each angle on the inside of the star is an obtuse angle. there are 5 obtuse angles and no right angles.
An obtuse triangle has 1 obtuse angle and 2 acute angles
A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
Just one.
Triangles do not have to have any obtuse angles but they can have one.
They will be acute angles.
Yes. It must have an obtuse angle.
