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.
an obtuse angle has 2 angles.
Obtuse angle: _/-acute

An obtuse angle is over 90 degrees but less than 180 degrees.
An obtuse angle is any angle greater than 90 degrees.
None. An acute angle is smaller than an obtuse angle.
*does, not dose, btw. =)
None. The angles of an octahedron are solid angles and the term "obtuse" does not apply to solid angles.
An octahedron have 6 obtuse 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.
Triangles do not have to have any obtuse angles but they can have one.

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
yes, there can be an obtuse internal angle in a triangle, but keep in mind that the other two angles' sums plus the obtuse angle can only equal 180 degrees (meaning that the other non-obtuse angles will be very small acute angles)
a trapezium has two obtuse angles or one if it has a right angle
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!)
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 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..
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.
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
Just one.
They will be acute angles.
Triangles do not have to have any obtuse angles but they can have one.
