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.
The 'classic' arrow-head shape has 7 angles.
An arrowhead is a quadrilateral and in common with all quadrilaterals its 4 interior angles add up to 360 degrees.
No but as a 4 sided quadrilateral its 4 interior angles add up to 360 degrees
The sum of the interior angles is 360 and the sum of the exteriors is 360 also.
an arrowhead has 4 angles. but no, you can't make an arrowhead out of only right angles.

No
The arrowhead has zero right angles.
It has one pair of opposite angles that are equal but not two.
The 'classic' arrow-head shape has 7 angles.
yes
only if it is an equilateral triangle
Two or three.
An arrowhead perhaps
If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!If both angles are 180, their sum is 360!
The exterior angles sum to 3600 , but the interior angles sum to 23400.
