It depends on whether you mean area, perimeter, sides, angles, diagonals, etc.
A quadrilateral has 2 diagonals. It does not matter whether it is convex or not.
no
If any of the angles is greater than 180 degrees, the quadrilateral is concave.
It may or may not be.
A concave quadrilateral. An arrowhead or a delta, for example.
A quadrilateral has 2 diagonals. It does not matter whether it is convex or not.
What is the sum of the measures of the angles of a convex quadrilateralwill this property hold if the quadrilateral is not convex?
no

concave
A concave quadrilateral would be a non-convex quadrilateral. * * * * * Also known as delta or arrowhead or chevron.
It would be a concave quadrilateral The link below has some pics.
A normal 2-D quadrilateral would be neither convex or concave. There are three-dimensional quadrilaterals, such as prisms, but it would depend on the shape.
