Yes a square always has 4 right angles but a rhombus never has any right angles.
A parallelogram with 4 right angles is a rectangle.
A rectangle has 4 right angles
The arrowhead has zero right angles.
yes
No but as a 4 sided quadrilateral its 4 interior angles add up to 360 degrees
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.
Depends. Most of the time the angles are acute or obtuse
An arrowhead is a quadrilateral and in common with all quadrilaterals its 4 interior angles add up to 360 degrees.
All apart from square, rhombus, kite and arrowhead.
No
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.
3
The 'classic' arrow-head shape has 7 angles.
