Yes.
No, a scalene triangle, for example, is a convex poygon but it is not regular.
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.
No. There can be no regular concave polygon.
A regular polygon.
It is a regular polygon.
No, as long as the polygon is convex.
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.
That is called a regular polygon.
Only when the polygon is a regular convex polygon. Such as an equilateral triangle, or a square, or a regular pentagon.
