Does a quadrilateral have a convex or a concave angle?
concave
Can a concave quadrilateral be regular?
No.
What is non convex quadrilateral?
A concave quadrilateral. An arrowhead or a delta, for example.
Is a quadrilateral convex or concave?
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.
Is a concave quadrilateral less than 180 degrees?
The sum of the interior angles of a quadrilateral is 360 degrees (not 180). The sum of the exterior angles is also 360 degrees. Whether the quadrilateral is convex or concave is not relevant.
What is a concave quadrilateral?
A concave quadrilateral would be a non-convex quadrilateral. * * * * * Also known as delta or arrowhead or chevron.
Does a quadrilateral have a convex or a concave angle?
concave
Can a concave quadrilateral be regular?
No.
What is a reenterant quadrilateral?
A concave quadrilateral - like an arrowhead or chevron.
Can a concave quadrilateral be a regular polygon?
No.
Can a concave quadrilateral tessellate?
yes it will...
What is non convex quadrilateral?
A concave quadrilateral. An arrowhead or a delta, for example.
Is a trapezoid concave?
No. A trapezoid has two parallel sides. This is not possible in a concave quadrilateral.
What is a non-convex quadrilateral?
It would be a concave quadrilateral The link below has some pics.

Can a quadrilateral have each of 4 angles a different measure?
Yes, be it a common convex quadrilateral or a concave quadrilateral. For a convex quadrilateral, the most obvious example is a irregular trapezium, where the upper base and the lower base are of different length, and the slanted sides are of different length. It is similar for a concave quadrilateral.
