Draw any circke and mark point A, B and C such that ( c) C is in the exterior of the circle.

Draw any circke and mark point A, B and C such that (b) B is in the interior of the circle.

Draw any circke and mark point A, B and C such that (a) A is on the circle.

AB is a diameter of a circle and C is any point on the circumference of the circle, then :

If a point 'C' lies between two points A and B such that AC =BC , then prove that AC=1/2 AB . Explain by drawing the figure.

In the given figure, two circles with centres O and O' touch externally at a point A. A line through A is drawn to intersect these circles at B and C. Prove that the tangents at B and C are parallel.

If a point C lies between two points A and B, such that AC=BC , then prove that AC=1/2 AB . Explain by drawing the figure.

Three distinct points A, B and C are given in the 2 -dimensional coordinate plane such that the ratio of the distances of any one of them from the point (1,0) to the distance from the point(-1,0) is equal to (1)/(3) . The circumcentre of the trianglt A B C is at the point

There are five points A,B,C,D and E. no three points are collinear and no four are concyclic. If the line AB intersects of the circles drawn through the five points. The number of points of intersection on the line apart from A and B is

If a,b,c are unit vectors such that a+b+c=0 , then find the value of a.b+b.c+c.a .

If A,B and C are any three sets , then A x (B nn C) is :
