only if it is an equilateral triangle
None they all ALL different!
It has one pair of opposite angles that are equal but not two.
It could be an arrowhead (delta) or a kite.
The arrowhead has zero right angles.
no, all sides are equal but only all opposite angles are equal, except the special case of a square where all angles are equal to 90 degrees

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