Yes, but not a polygon (or polyhedron).Consider a quadrilateral with one diagonal. The end points of the diagonal are at odd vertices while the other two are even.
A polygon is any geometric 2-D shape. A Quadrilateral is a polygon with four sides.
No vertices (0). a heart shape is not a polygon shape, only polygon shapes have vertices.
no
quadrilateral
No. A quadrilateral is a 2-dimensional shape with 4 edges, 1 face and 4 vertices.
A polygon is a plane (2-dimensional) shape bounded by straight lines. It can have 3 or more sides. A polygon with 4 sides is a quadrilateral.

Yes. To be specific, a trapezoid is a quadrilateral polygon. Polygon: a plane or figure that is formed by 3 or more segments, and each side only connects to 2 other sides.
A line connecting to non-adjacent vertices of a polygon is called a diagonal of the polygon. A triangle has no diagonals since each vertex is adjacent to the next. A quadrilateral has two diagonals.
