qus 1 - show me by fig. how a circle divides the plane, on which it lies in three parts.
qus2- prove that if the bisector of any angle of a triangle and the perpendicular bisector of its opposite side intersect, they will intersect n the circumcircle of the triangle.
plzzzzzzz........ give me the sol of this ques with concept of main topic of this ques
qus 3 - if O is the centre of a circle of a circle of radius r and AB is a chord of the circle at a distance r/2 from O, then find angle BAO.
qus 4 - Let C be the mid point of arc AB of a circle such that m arc AB = 183 degree. if the region bounded by the arc ACB and line segment AB is denoted by S, then where centre O of the circle lies?
qus 5 -If A and B are two points on acircle such that m( arc AB) = 260 degree. find A possible value for the angle subtended by an arc BA at a point on the circle.
qus 6 - if AB is a chord of a circle , P and Q are the two pints on the circle different from A and B, then prove that angle APB+ angle AQB = 180 degree or angle APB= angle AOB.
qus 7 -If ABC is arc of acircle and angle ABC = 135 degree, then prove that the ratio of arc ABC to the circumference is 1:4.
