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.
An arrowhead is a quadrilateral and in common with all quadrilaterals its 4 interior angles add up to 360 degrees.
360 degrees
No but as a 4 sided quadrilateral its 4 interior angles add up to 360 degrees
All apart from square, rhombus, kite and arrowhead.

The arrowhead has zero right angles.
an arrowhead has 4 angles. but no, you can't make an arrowhead out of only right angles.
Two or three.
None they all ALL different!
No
It has one pair of opposite angles that are equal but not two.

Depends. Most of the time the angles are acute or obtuse
360 degrees
yes
only if it is an equilateral triangle
