Acute angles at the tip and two where the edge turns back, a reflex angle where it meets the shaft.
an arrowhead has 4 angles. but no, you can't make an arrowhead out of only right angles.
No
An arrowhead shape typically consists of a triangle or a series of angles that form a pointed end. In a simple triangular arrowhead, the internal angles sum to 180 degrees. If the arrowhead includes additional angles or extensions, the total degrees could vary, but the fundamental triangular portion remains 180 degrees.

An arrowhead perhaps
an arrowhead has 4 angles. but no, you can't make an arrowhead out of only right 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.
No
The arrowhead has zero right angles.
An arrowhead typically has two equal angles. The two angles are formed by the two sides of the arrowhead meeting at the tip. These angles are typically acute angles, each measuring less than 90 degrees.
It has one pair of opposite angles that are equal but not two.
The 'classic' arrow-head shape has 7 angles.
