What is a nonconvex polygon?
A nonconvex polygon is a concave polygon. All polygons with 4 or more sides can be concave. An arrowhead is an example of a concave quadrilateral. The back of an envelop (where the sides are folded and glued together) is a concave pentagon.
What type of polygon must have a diagonal such that part of the diagonal falls outside of the polygon?
Concave quadrilateral.
For a given number of side there exist both a regular concave polygon and a regular convex polygon?
A concave polygon cannot be regular because regularity requires all angles (and sides)to be of equal measure. Even if you drop the requirement of regularity, there cannot be a concave triangle.
Is A Rectangle An Irregular Or Regular Quadrilateral?
its a regular quadrilateral * * * * * No it is NOT! The sides of a rectangle, in general, are not all the same length and, therefore, it is not a regular polygon.
Can a concave polygon be a regular polygon?
No.No! It is not possible.Regular polygon:Polygon in which all the sides are equal and all the interior angles are equal is called as a regular polygon.Concave polygon:A polygon that has one or more interior angles greater that 180o is called as a concave polygon.It is not possible to have polygon with all sides equal and greater than 180o.Source: www.icoachmath.com it is possibleA concave polygon had to be irregular.
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 every quadrilateral a regular polygon?
No not every quadrilateral can be a regular polygon.
What is defined to be a quadrilateral in which both pairs of opposite sides are parallel a regular polygon b concave polygon c parallelagram d octagon?
Dragon is the answer
What type of quadrilateral can not be a regular polygon?
which type of quadrilateral is never a regular polygon
Is a concave polygon a regular polygon?
No, a concave polygon cannot be a regular polygon.
Can a concave quadrilateral be regular?
No.
What is a nonconvex polygon?
A nonconvex polygon is a concave polygon. All polygons with 4 or more sides can be concave. An arrowhead is an example of a concave quadrilateral. The back of an envelop (where the sides are folded and glued together) is a concave pentagon.
Why must concave quadrilaterals be irregular?
A regular polygon has all its angles of equal measure, and its sides of equal length. In the case of a quadrilateral, that would mean a square. A concave quadrilateral must have at least one reflex angle and so cannot be a square. So it cannot be regular.
Why can't a concave quadrilateral be regular?
By definition, a regular polygon has all interior angles the same, but a concave polygon has some interior angles that are not identical. Also, it violates the axiom that all vertices lie on a circle.While it is possible to construct a polygon with equilateral sides, to be concave would require a form that is equally convex and laterally opposite. (An example is a 'solid arrow shape.')
What are the similarities between regular polygon and a concave polygon?
A regular polygon is a special kind of convex polygon - one in which all the sides are of the same length and all the angles are equal. Convex and concave polygons form disjoint sets: so no concave polygon can be regular.
What type of polygon must have a diagonal such that part of the diagonal falls outside of the polygon?
Concave quadrilateral.
Can a concave qudrilateral be a regular polygon?
no
