Circle Properties
- The circles are said to be congruent if they have equal radii.
- The diameter of a circle is the longest chord of a circle.
- Equal chords of a circle subtend equal angles at the centre.
- The radius drawn perpendicular to the chord bisects the chord.
- Circles having different radius are similar.
