Let BC is a fixed chord of a given circle with centre P. A is a variable point on it. Find the locus of the mid point of the line segment AC.
Girdle with radius one -third of the given Circle
Circle with radius one-fouth of the given Circle
Circle with radius half of the given circle
None of these
Let mid points of PC and AB are Q and R respectively.
Hence QR = PA/2 = half of the radius of given circle.
Hence locus of R is a circle with centre at mid point of line PC,
and radius is half of the given circle.
