The product of the distances of the incentre from the angular points of a `triangleABC` is

The distance of the incentre of the triangle ABC from A is

Write the distance of the point from plane.

The distance of the incentre of DeltaABC from A is

The distance of the point (a,b) from the origin.

If P denotes the perimeter and S denotes the sum of the distances of a point within a triangle from its angular points, then

The abscissa of a point is the distance of the point from

Distance of point from given line

The distance of the point (-a,b)from origin is,

In a rectangular hyperbola, prove that the product of the focal distances of a point on it is equal to the square of its distance from the centre of the hyperbola .

In !ABC , x , y , and z are the distance of incentre from angular points A , B ,and C respectively . If (xyz)/(abc)=(lamdar)/s , then lamda =
