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.
A rhombus have 2 obtuse angles
There are 3 obtuse angles in a heptagon.
One and the two others are acute angles
one
Triangles do not have to have any obtuse angles but they can have one.
No
An arrowhead typically has two acute angles. These angles are formed at the tip of the arrowhead, allowing it to have a pointed shape. The remaining angles at the base of the arrowhead are often obtuse or right angles, depending on the design.
Depends. Most of the time the angles are acute or obtuse
It has two obtuse angles
The arrowhead has zero right angles.
A rhombus have 2 obtuse angles
There are no angles they are all obtuse angles
A trapezium has one or two obtuse angles.
There are 3 obtuse angles in a heptagon.
It can have at most one obtuse angle.
an arrowhead has 4 angles. but no, you can't make an arrowhead out of only right angles.
An obtuse triangle can have no right angles, and has two equal angles.
