An arrowhead
A chevron or arrowhead.
Acute angles at the tip and two where the edge turns back, a reflex angle where it meets the shaft.
Possibly in the form of an arrowhead providing that its 4 interior angles add up to 360 degrees
Yes. The two angles on either side of the reflex angle are normally equal.
Reflex angle
Yes.
An arrowhead
A chevron or arrowhead.
Yes - a chevron or arrowhead.
The difference is surely that an arrowhead has one reflex internal angle where a kite does not.
The shape described is a kite, which is a quadrilateral with two pairs of equal adjacent sides and one reflex angle. A kite has an axis of symmetry along the line connecting the midpoints of the non-congruent sides. The reflex angle in a kite is typically greater than 180 degrees, creating a distinct shape that is not a regular quadrilateral.

A bit like a chevron or an arrowhead.
Acute angles at the tip and two where the edge turns back, a reflex angle where it meets the shaft.

This is an arrowhead quadrilateral.
