How do you identify the parts of a circle?
Important Circle Parts
- Radius: The distance from the center of the circle to its outer rim.
- Chord: A line segment whose endpoints are on a circle.
- Diameter: A chord that passes through the center of the circle.
- Secant: A line that intersects a circle in two points.
Who found the shape circle?
The greeks considered the Egyptians as the inventors of geometry. The scribe Ahmes, the author of the Rhind papyrus, gives a rule for determining the area of a circle which corresponds to π = 256 /81 or approximately 3. 16.

All diameters are chords, but not all chords are diameters. A plane is a flat surface that extends without end in all directions.

Which is the best example of a circle?
