It has one pair of opposite angles that are equal but not two.
only if it is an equilateral triangle

Two or three.
Depends. Most of the time the angles are acute or obtuse

yes
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.

Yes. The two angles on either side of the reflex angle are normally equal.
A kite or an arrowhead.
an arrowhead has 4 angles. but no, you can't make an arrowhead out of only right angles.
No but as a 4 sided quadrilateral its 4 interior angles add up to 360 degrees

This is an arrowhead quadrilateral.
