An oval is a closed curve in a plane which "loosely" resembles the outline of an egg. The term is not very specific, but in some areas it is given a more precise definition, which may include either one or two axes of symmetry. In common English, the term is used in a broader sense: any shape which reminds one of an egg.

In geometry, a star polygon (not to be confused with a star-shaped polygon) is a concave polygon. Only the regular star polygons have been studied in any depth; star polygons in general appear not to have been formally defined.

The "heart shape" (♥) is an ideograph used to express the idea of the "heart" in

its metaphorical or symbolic sense as the center of emotion, including affection

and love, especially (but not exclusively) romantic love.

In mathematics, a spiral is a curve which emanates from a

central point, getting progressively farther away as it revolves around the

point.

A kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. Kite quadrilaterals are named for the wind-blown, flying kites, which often have this shape and which are in turn named for a bird.

BACK

A triangle is a polygon with three edges an

d three vertices. It is one of the

basic shapes in geometry.
