Locus OF point if angle between two vectors given || equation OF line and circle

Introduction , definition OF circle and locus, equation OF circle, terms related to circle like as chord, reagent, sector, arc etc. area OF sector and segment, orientation OF circle wrt to line- no point common,1 point common and 2 point common

If the perpendicular bisector of a chord AB of a circle PXAQBY intersects the circle at P and Q, prove that arc PXA cong"arc "PYB .

Locus and nine point circle

The locus of feet of perpendiculars from the focii upon any tangent is an auxilliary circle.

If two chord of a circle (or of congruent circles) are equal,then their corresponding arcs.(minor,major or semi-circular) are congruent.

The locus of the point from which perpendicular tangent and normals can be drawn to a circle is
