what is the name of a smooth curved line around the outside of a regular polygon
The line that goes around, or envelopes, a circle is the circumference of the circle. It is found by multiplying the diameter of the circle, which is a line that crosses the center, by pi.
A diameter bisects a circle.
That's a "radius" of the circle.
It is the circle's circumference

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.

The line segment is the radius of a circle that connects the center of a circle to any point on its circumference.
The other name for the line of symmetry of a circle is the diameter. The diameter of a circle is a line segment that passes through the center of the circle and has endpoints on the circle itself. It divides the circle into two equal halves, making it a line of symmetry. This means that if you were to fold the circle along the diameter, both halves would perfectly overlap.
