👉 A cardioid is a type of surface curve in mathematics, particularly geometry. It is a family of curves that are symmetric about their center and have an axis of symmetry through their center.
Here's how you can define it:
1.
Symmetry
: A cardioid has two symmetries: it is symmetric about its center (the point where the curve meets the x-axis) and its axis of symmetry, which is perpendicular to this line.
2.
Axis of Symmetry
