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.

How can you tell whether a quadrilateral is convex or not convex?

If any of the angles is greater than 180 degrees, the quadrilateral is concave.

What is a non-convex quadrilateral?

It would be a concave quadrilateral The link below has some pics.

Could a concave quadrilateral have more than one reflex angle?

A reflex angle is over 180 degrees, but the sum of the angles in a quadrilateral, concave or convex, is 360. Therefore, since 180+180=360, you can't have any more degrees even without the amount over 180 that the reflex angle has.

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.

The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?

A square is an example of a quadrilateral that is both a regular concave polygon and a regular convex polygon?

No. There can be no regular concave polygon.

Is an acute angle a concave or convex angle?

All angles < 180 degrees are concave. An acute angle is < 90 degrees. So, all acute angles are concave.

What is the difference between a concave polygon and a convex polygon?

Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
