The perpendicular distance of a corner of uni cube from a diagonal not passing through it is

Find the perpendicular distance of an angular point of a cube from a diagona which does not pass through that angular point.

Cube: Volume: SA: diagonal

Find the equation of a curve passing through the point (1.1) if the perpendicular distance of the origin from the normal at any point P(x,y) of the curve is equal to the distance of P from the x-axis.

A curve passing through the point (1,2) has the property that the perpendicular distance of the origin from normal at any point P of the curve is equal to the distance of P from the x-axis is a circle with radius.

The algebraic sum of the perpendicular distances from the vertices of a triangle to a variable line is ‘O', then the line passes through the ------ of the triangle

If the diagonals of a cyclic quadrilateral are perpendicular to each other, show that the line passing through the point of intersection of diagonals and midpoint of a side is perpendicular to the opposite side.

If each line of a pair of lines passing through origin is at a perpendicular distance of 4 units from the point (3, 4) , then the equation of the pair of lines is
