A RADIUS connects the center of a circle to any point on the circle.
The radius of a circle connects its center to its circumference.
If it connects the center of the circle to the edge, it is the radius. If it is a straight line that connects the edges of a circle through the center, it is the diameter.
The question is: Is A radius is an angle that connects to any point on the circle to the center of that circle? A Radius is a straight line coming from any point of the circle to the center of the circle. And remember that the Diameter is a straight line coming from any point of the circle and going straight through the center to the other side of the circle. The Radius is ALWAYS half of the Diameter; and, the Diameter is ALWAYS twice the Radius.
Always
The Radius
The line from the center of a circle to a point on the circle is the radius.
The line segment is the radius of a circle that connects the center of a circle to any point on its circumference.
That's a "radius" of the circle.
The line from the center of a circle to a point on the circle is the radius.
Radius
the radius is the distance of half-way across a circle. While some people would say it never connects 2 points on a circle, others will tell you that it connects the middle to the edge
