Question

A round plane figure whose boundary (the circumference) consists of points an equal distance from a fixed point in the center is called what

Answer 1

Circle

Step-by-step explanation

We want to find the name of a round plane figure that has a boundary such that points on that boundary are an equal distance from a fixed point in the center.

To represent this diagramatically, we have:

As we can see, A and X are the same distance from O.

All the points on its circumference equidistant from the center.

This shape is called a circle.
