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
It has one pair of opposite angles that are equal but not two.
The 'classic' arrow-head shape has 7 angles.
A trapezium has 4 right angles...Correction: it has 4 angles but they are not right angles. A structure/shape with 4 right angles is a rectangle or square.
360 degrees
