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.

Does an acute triangle have 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.
How many obtuse angles does a obtuse triangle have?
Triangles do not have to have any obtuse angles but they can have one.
How many angles in a acute straight reflex and obtuse angle?
29
Which triangle has 1 acute angle and 1 obtuse angle?
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
Can one of the internal angles of a triangle be an obtuse angle?
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)
How many obtuse angles has a trapezium?
a trapezium has two obtuse angles or one if it has a right angle
How many obtuse angles in a triangle?
A triangle can have at most one obtuse angle, but triangles do not necessarily have any obtuse angles.
How many obtuse angles are there in a square?
There are no obtuse angles in a square. A square is a perfect 90 degree angle.
How many obtuse angles are in a right angle?
There are 3 obtuse angles. All 3 exterior angles are obtuse. (This is, admittedly, a bit of trick question!)
Does an acute triangle have 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.
How many angles in a obtuse angle?
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..
How many acute angles are in a 5 pointed star?
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.
Is a trapezold a acute obtuse or right angle?
A trapezoid contains either:two acute angles and two obtuse angles orone acute angle, one obtuse angle and two right angles.
What are the angles in an obtuse triangle?
An obtuse triangle has 1 obtuse angle and 2 acute angles
How many right angles can be in a obtuse angle?
Just one.
If an obtuse angle is bisected then are the resulting angles obtuse or acute?
They will be acute angles.
How many obtuse angles does a obtuse triangle have?
Triangles do not have to have any obtuse angles but they can have one.
