Some Properties Related to Circle

Category : JEE Main & Advanced

  (1) Angles in the same segment of a circle are equal i.e., \[\angle APB=\angle AQB=\angle ARB\].


(2) Angles in the alternate segments of a circle are equal.  


(3) If the line joining two points A and B subtends the greatest angle \[\alpha \] at a point P then the circle, will touch the straight line \[XX'\]at the point P.    


(4) The angle subtended by any chord at the centre is twice the angle subtended by the same on any point on the circumference of the circle.
