Circles
A circle is made of points that are the same distance from a fixed point called the center. There are different parts to a circle.
The center is the point in the middle of a circle.
A radius is a line segment that has one end point on the center and the other end point on the circle.
A diameter is a line segment that has both end points on the circle and runs through the center.
The circumference is the distance around the circle.
