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.
A concave quadrilateral. An arrowhead or a delta, for example.

What is the sum of the measures of the angles of a convex quadrilateralwill this property hold if the quadrilateral is not convex?
no
If any of the angles is greater than 180 degrees, the quadrilateral is concave.
how many sides convex quadilaterals have
yes

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.
It is a convex quadrilateral, as the remaining angles could be any two angles with a sum of 180 degrees.
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.
