Yes. The two angles on either side of the reflex angle are normally equal.
yes
A kite or an arrowhead.

Yes. The two angles on either side of the reflex angle are normally equal.

only if it is an equilateral triangle
None they all ALL different!
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
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.
This is an arrowhead quadrilateral.
No
The arrowhead has zero right angles.
