A squashed circle with no straight edges is called an "ellipse." An ellipse is a geometric shape that resembles a flattened circle and is defined by its two focal points. The distance from any point on the ellipse to these focal points has a constant sum.

A diameter bisects a circle.
A straight line from the center to the edge of a circle is called a radius. The radius measures the distance from the center to any point on the circumference of the circle.
A tangent. And it does not need to be a circle - it can be any curve.
