geometry
A heart shape isn't a polygon because a heart has to curves. The description of a polygon doesn't list curves.
Three
It is geometry.
apolygon is a shape that has no curves ,is closed, and has more then three sides
Geometry is the branch of mathematics that is concerned with the properties and relationships of points, lines, angles, curves, surfaces, and solids.
The pure mathematics of points and lines and curves and surfaces.

To a great extent, differential calculus is concerned with the slopes of curves - or with things that can be graphically represented as slopes, such as speed (the speed graph is a curve in a distance vs. time graph).
