DIAMETER & CHORD OF A CIRCLE

__DIAMETER & CHORD OF A CIRCLE__

**Chord of a Circle –**

**A line segment joining two points on a circle will be considered as a chord of the circle. In the figure, PQ, PR, and PS are chords of the circle. In the figure, PQ, PR, and PS will be considered as chords of the circle**

__Diameter Of The Circle –__

**A chord that passes through the center of the circle will be considered as the diameter of the circle. In the figure above, PQ maybe a chord passing through the middle ‘O’. so the line segment PQ is that the diameter of the circle. The length of the line segment PQ will be called the diameter of the circle. In other words, the diameter is that the length of the longest chord of a circle.**

**Now, PQ = PO + OQ = radius + radius = 2 X radius**

**Therefore,**

** Diameter**

**Radius = --------------, Diameter = 2 X radius**

** 2**
