What is best described as all the points on a plane that are the same distance from a single point called a center?

The circle is best described as all the points  that are the same distance from a single point as its center.

distance between the midpoint and the border of circle are called radius of circle.

because a circle is special type of ellipse

The term that is describes here is: Circle.

Circle--

A circle is the collection of all the points in the plane that are equidistant ( at a equal distance) from a fixed point on a plane.

The fixed point is known as the center of the circle.

and the fixed distance is known as the radius of the circle.

Also, the diameter of the circle is the line that passes through the center of the circle and has end points on the circumference of the circle.

Diameter is twice the radius of the circle.

           Hence, the answer is:   Circle

the first question mark is 6 and the second question mark is 26 (the square root)
