That means a heart curve.
A cardioid has 1 line of symmetry.
A cardioid is one possibility. See link, below.
Isosceles triangle, kite. -improvement: an isosceles triangle actually has three lines of symmetry, equal to the number of sides. It is easy to design irregular polygons with an odd number of sides that have just one line of symmetry. A parabola. Many more functions that are more complex - cardioid, for example.
A cardioid has 1 line of symmetry.
A cardioid is a type of geometrical shape that is a type of limacon. A cardioid is formed when a circle is rolled around another circle creating a curved shape.

The cardioid or unidirectional microphone is the most common type of microphone pickup pattern. It is used everywhere, from voice to instruments.
A cardioid is a heart shaped circle with another circle thing going around it always meeting up at the middle of the circle thingy...I think?
The main difference between a supercardioid and cardioid microphone pattern is the directionality of sound they pick up. A supercardioid microphone is more focused and picks up sound from the front while rejecting more sound from the sides and rear compared to a cardioid microphone, which picks up sound mainly from the front but also captures some sound from the sides.
The cardioid can be found in the caustics of cups, the shape of a lily leaf, the shape of an apple seen from the side, the construction of unidirectional microphones and the central bulb of the Mandelbrot set.

The main difference between a cardioid and a supercardioid microphone pattern is the directionality of sound pickup. A cardioid microphone picks up sound mainly from the front and slightly from the sides, while a supercardioid microphone is more directional and picks up sound primarily from the front with a narrower pickup angle.
A super cardioid microphone is a type of directional microphone that is highly sensitive to sound coming from the front and rejects sound from the sides and rear. It has a narrower pickup pattern compared to other microphone types like cardioid or omnidirectional, making it ideal for capturing sound from a specific direction while minimizing background noise.
A cardioid is the line a point on the edge of a circle traces when the circle is rolled around a circle of equal radius. A nephroid is the line a point on the edge of a circle traces when the circle is rolled around a circle of twice the radius.
