The circumference is the length of the outer rim of the circle.
What is the tangent?

What is the secant?
The secant is similar to a chord, but it passes through the outer rim of the circle.
What is a sector?
A sector is the part of a circle that lies between two radii.
What is a segment?
A segment is the part of a circle that lies between the chord and the outer rim of a circle.
