Circle- Diameter, Chord, Center, & Radius Worksheets

What are the Measures of a Circle: Diameter, Chord, Center, & Radius? The first ever shape that we come across is the shape of a circle in geometry. A circle is round shaped figure that can be easily drawn with a center point which is just a radius away. An interesting thing about circle is that the distance from its radius to any point on the circle is the same. When you talk about circles, there are three lines that you have to consider; the radius, the chord, and the diameter. Diameter: The diameter of a circle is the line segment that passes through the center of the circle. The diameter is twice the radius. Chord: The chord refers to the line segment that connects two points on a circle. Radius: A circle's radius is the distance from the center point of the circle until any point on the circle. The radius tells you the size of the circle. In addition to being a line segment that connects the center point to anywhere on the circle, it is also one half of the diameter.
