An obtuse triangle can have no right angles, and has two equal angles.
There are 3 obtuse angles. All 3 exterior angles are obtuse. (This is, admittedly, a bit of trick question!)
A triangle can have at most one obtuse angle, but triangles do not necessarily have any obtuse angles.

It depends on they type of arrowhead you have. If it is a arrowhead in the shape of a directional arrow, there are no obtuse angles. The most possible obtuse angles is 1.
