A concave quadrilateral would be a non-convex quadrilateral. * * * * * Also known as delta or arrowhead or chevron.

A trapezoid (UK trapezium) is a quadrilateral has only one pair of parallel sides. Otherwise, there are many irregular quadrilaterals that have no parallel sides, such as a kite or dart shape, and these include both concave and convex quadrilaterals.
No.
A concave quadrilateral - like an arrowhead or chevron.
a quadrilateral isa polygon with four sides and four vertices. Sometimes the word quadrangle is used. The interior angles add up to 360 degrees. Quadrilaterals are either simple (not self- intersecting) or complex (self-intersecting). Quadrilaterals and polygons in general, are broadly divided into two groups: convex and concave polygon.
No.
A chevron or arrowhead.
