circumference
The answer will depend on what the "certain distances" are for each point.
Perimeter is a term applied to the boundary of a shape or object. It is the distance around the outside of it. A link is provided below.
The quadrant is the one of the four quaters of a circle. It is the math term for a 1/4 of a circle.

The distance around a circle is its circumference
"Circle". That "same distance" is the radius of the circle, and that "given point" is the center of the circle.

The distance around a circle is its circumference.
The term that describes the point equidistant from all points on the boundary of a circle is the "center" of the circle. This point is located at the midpoint of the radius, and every radius drawn from the center to the circumference is of equal length.
===> "circle", with center at the "single point" and radius of the "certain distance".
A circle. However, that DOES depend on the Euclidean metric being used for measuring distance.
The term that describes the distance from the crest to the trough of a wave is called the amplitude.
That's called the 'radius'.
